A Note on Platform Sutra by Dr Ramesh Chandra Mukhopadhyaya

The Platform Sutra opens with an address by Bhagavan Hui Neng. It
opens with a description of the audience that consisted of brilliant
men  and women from different walks of life.There were gopvernment
officials Confucian scholars Taoists bhikkhus and bhikkhunis and
others.This reminds of the openings of the Mahayana sutras where
Buddha addresses an audience consisting of Buddhas and bodhisattvas
and seers and bhikkhus and bhikkhunis of different levels of
attainment and kings and princes.

Bhagavan  in order to dwell on the essence of Buddhism at the outset
tells us how he realised the same in his own life.Indeed Buddhism is
not being taught here as a discipline meant for Philosophy Honours
students or for students of Comparative Philosophy.Bhagavan is about
to teach Buddhism so that it transforms our body and mind, so that it
transforms our whole beings so that we could be Buddhas ourselves. And
the best way teach how one could be a Buddhists and enlightened one
had better recount how one became enlightened. This is where
bigraphies and auto biographies are essential..Biographies and auto
biographies give us case studies of men who crossed the Grand Canyon
of ignorance and reached the bower of bliss.

So the Platform Sutra now flows into an autobigraphical note where the
speaker Bhagavan Hui Neng tells his own story.

Bhagavan Hui Neng recounts his story. His father was a government
official . But as ill luck would have it , he died when Hui Neng was a
mere child. So his mother had a hard time.Hui Neng used to collect
firewood and sell the same in the market in Canton. One day he heard
someone recite the Diamond Sutra. At once he attained enlightenment.He
went to the man who was reciting the sutra and learnt that it was Hung
Yen who had taught him to recite the sutra. Both laymen and those who
are initiated in the lore of Buddhism had better recite the sutra.
Because that is how  one could directly become a Buddha.

Although Sakyasinha of Kapilavastu and many other Buddhas were born
with a silver spoon  Bhagavan Hui Neng had a different past. Very
early in his life he lost his father . So he had lot of hardship.But
listening to the Diamond sutra enlightened him. This speaks of sudden
enlightenment. Whether enlightenment could take place  all of a sudden
or not is always debated.But we feel that whenever enlightenment takes
place it takes place all of a sudden. The reason is
simple.Enlightenment gives one a vision of life and existence that is
qualitatively different from the ordinary man’s perception of the
universe. There might be numerous planes of enlightenment and
perception . Higher and higher the person might excelsior from one
plane of enlightenment to another. And every leap is characterised by
suddenness. Sakyasinha Buddha saw myriads of his former births and
death as if in a flash during the hour of his enlightenment. It
happened with suddenness.In fact no one can be one fourth Buddha and
half Buddha and so on.Realisation implies phase shift. It is something
like water turning into vapour. At a time quantum the water all of a
sudden turns into vapour.  But this suddenness is also apparent.
People who toiled hard through numerous lives all of a sudden attains
enlightenment.True that Hui Neng was not initiated in the Buddhist
lore. But in his earlier lives he must have had journeyed along the
tao. The fruition came to him all of a sudden in his life when he was
a firewoodseller in Canton. The man who was reciting the Diamond Sutra
told Hui Neng that one could be directly a Buddha according the
patriarch Hung Yen 

Hui neng was a poor firewood seller . He was not educated. While at
the Canton bazaar busy getting and spending he chanced upon the chant
of Diamond Suta. And at once he was enlightened. He went to the person
and heard of Bhagavan Hung yen. Bhagavan Hung Yen told the person that
chanting of the Diamond Sutra can manifest Buddha nature in the
mendicants as well as the laity. Hui Neng at the advice of his
neighbours made up his mind to go and meet Bhagavan Hung Yen.Hung Yen
lived in a place roughly thirty days’ walk away from Canton. One of
the acquaintances of Hui Neng helped Hui Neng settle things for his
mother so that she does not starve during his absence.Hui Neng now set
out for Hung Yen and reached his place in less than thirty days. He
paid his obeisance to the Fifth patriarch of the Chan school and told
him that he had come a long way to pay the patriarch his respects. He
told the patriarch that he wanted to be a Buddha. Hung Yen said that
Hui Neng had come from  Ling Nan and hence a barbarian. Humg Yen
wondered whether a barbarian could be a Buddha or not. Hui Neng came
from South China and people of South China were barbarians. But
enlightenment had already opened itself before Hui Neng. So he had no
hesitation to speak the truth. He said in the contingent one might
belong to the South or to the North, one may be a barbarian or not.
But Buddha nature is everywhere the same. Buddhanature in every one is
the same. So discriminating people as barbarian or civilized does not
conform to the Buddha nature.

Once upon a time, there was a very beautiful young man whose name was Mon Pa. When it was dusk, he used to sit in a cloister and meditated on the  transitoriness  of the world of eye and ear. Right then, an angel used to appear before him and nestle close to him. The young man used to enjoy his company. But as soon as the night set in, the angel would vanish. The young man did not know the whereabouts of the angel. One day he hit upon a plan. He softly tied a thread with the belt of the angel. One end of the thread however remained with the young man. When the angel vanished, where he went could be now easily detected. The young man followed the thread and went to a forlorn grotto where the angel lived. But that is not our point. We want to illustrate hereby how a thread could lead one from the known to the unknown. Or else, how a thread could unravel a mystery. Buddhist literature is loaded with Suttas or Sutras. The Pali word Sutta may have been derived from the Sanskrit Sukta or Su  Ukta meaning well said or a noble speech. The Buddhist Suttas should be deemed as noble speeches. Most of them were delivered by Lord Buddha himself. But Sutra could be also understood as a thread that might lead one to unravel some mystery not decoded here- to- before. The freaks of history and the logic of affairs spread the message of Buddha far and wide past the Himalayas and past the Taklamakan desert. And Hui Neng from South China got at the heart of Buddhist way of life and became a Buddha or an Enlightened One himself. 

There were many religions and philosophical systems prevalent in China during Huineng’s time. There were the Confucians. There were the followers of Lao Tse. Also there were the followers of Lord Buddha. Many of them were government officials. They were keen to learn what truth is and how should one reach the truth. At their instance, Bhagvan Hui Neng delivered a speech in a stoa or a lecture hall. His speech stands out as a monument in course of the endless discourse of man on truth. It is known as the Platform Sutra. It is no doubt a well spoken speech which is time and again. It is often aphoristic loaded with signs. Reticence and economy of words characterize the speech. Thus the Platform Sutra being a Sutra  seems to give us the thread following which we might reach the mysterium tremendum that baffles all inferences and languages. We propose hereby to read  the first chapter of the Platform Sutra from the standpoint of the Close Reading School with high hopes to reach some treasure island.  The Close Reading School focuses on the text without taking into account any extratextual context whatever.The text for us is the Palatform Sutra as translated by Christian Humphreys and Wong Mou Lam. Close Reading School focuses on the text without taking into account any extratextual context whateve.Therefore we are not joining in the debate as to whether the speech of Master Hui Neng has been put down in the extant Platform Sutra ad verbatim or not or whether Hui neng was really christened as the sixth patriarch of the Zen community or not .Whatever context has been referred to in the text only---or the cotext  wiil be used in course of our close reading

The Platform Sutra opens with an autobiographical note. Bhagvan Hui Neng recounts his childhood. His father was a government officer. But may be he could not please his boss and hence he was dismissed from his post and banished to be a  commoner in Xin Zhou in Guangdong  As ill luck would have it he passed away when Master Hui Neng was a mere child. The mother and the little Hui Neng now  moved to Canton. He did not get any school education. He did not know how to read or write even. The cup of life was dealt to Hui Neng in a different way. Since his childhood he used to go to the forest and fell trees. He took wood there from and went to the city market for selling them. One day, when he reached the market with wood for sell, he heard someone chanting the Vajrachhedika Sutra and at once he was enlightened. 

One wonders whether it is at all possible to become enlightened all of a sudden hearing a particular chant. It is commonly assumed that one has to peruse lot of scriptures. One has to undergo lot of penance and meditation. Thereafter if one is fortunate enough , one might get a glimpse of the beatitude larking behind the show of the world. But on the surface Master Hui Neng  did not have to journey along such a rough road. The enlightenment was sudden. Apparently, he did not seek the truth or strive for it. Modern  physics, however speaks of the Butterfly Effect. If a butterfly flaps its wings in Calcutta , there might be a Tsunami in California. The cause might be mild but the effect could be tremendous and great.  A mere hearing of a chant of a Sutra might bring about a revolution in the perception of a man. A  peripeti or a sudden reversal of events took place in his life. The person who was chanting the Vajrachhedika or the Diamond Sutra told Master Hui Neng that he had visited the monastery of Master Hung Zen in North China. It was there that he learned the Sutra. The young Hui Neng felt that he must meet  His Holiness Master Hung Zen. Go he must. But how could he let alone his widow mother flung into the fire of chill penury and starvation. But another accident on the surface took place. The very man who was reciting the Vajrachhhedika Sutra  gave him a vast amount of money. With that , the widow mother could live through years to come amidst plenty even if she had not worked for her livelihood. Master Hui Neng settled things for his mother and then set out for the monastery of Hung Zen. This was the Abhiniskraman of Master Hui Neng.

It was a tiresome journey. Master Hui Neng walked for some thirty days . Finally he reached the monastery of Master Hung Zen. The first interview of Master Hui Neng with Master Hung Zen is time and again. Master Hui Neng said that  although  he was a very ordinary guy he wanted to be a Buddha or an enlightened one. To that end, he wanted to be initiated by Master Hung Zen. But the latter smiled on the other side of the face and exclaimed that the people from South China were barbarians. And it goes without saying Master Hui Neng hailed from South China only. But Master Hui Neng was not at all dismayed. He readily answered that when one understands what enlightenment is ,one does not know how to distinguish north from the south or east from the west.  This is not all Master Hui Neng further observed that may be in the contimgent he was a barbarian  while His Holiness Hung Zen was not , but   Buddha nature doesnot admit of any such distinction .Master Hui Neng’s answer clearly shows that his perceptions were different from those of the common run of men. Besides Master Hui Neng did not hesitate to express what he felt in front of the great preceptor Master Hung Zen although he prayed for initiation from the latter. The conversation drew attention of many a inmates of the monastery . Master Hung Zen summarily ended the conversation asking Master Hui Neng to go to the backyard of the monastery and work. 

As soon as Master Hui Neng reached the backyard of the monastery, someone ordered him to draw water and pound rice and hew wood for the kitchen. Master Hui Neng obeyed him. He never went to the lecture hall to listen to the sermons. He never went to the front side of the monastery to meet Master Hung Zen. In fact Hui Neng toiled like Prince Ferdinand in the household of Prospero. Hui Neng’s object of love was enlightenment or Buddhahood. After a long passage of time,  Master Hung Zen secretly visited Master Hui Neng and told him that he was positioned in the kitchen at the backyard of the monastery only with a purpose. Hung Zen said that Master Hui Neng must have understood the purport of his orders. Hui Neng said yes to his Master. 

This is a unique event. Love between the preceptor and his disciple must be very big. But there might be no display of the same. Even conversations between the two through verbal language is also not always necessary. 

One day, Master Hung Zen told an assembly of his disciples in the lecture hall that he was keen to choose his successor whom he would  hand over the begging  bowl and  the robe that he inherited from his preceptor. It was Bodhidharma who first preached Zen Buddhism in China. He was the Twenty-eighth in the line of the preceptors from Bhagvan Siddhartha Buddha himself. Bhagvan Bodhidharma was the first Zen patriarch in China. Hung Zen was the fifth patriarch in the line of Zen preceptors in China. The begging  bowl  and the robe  were inherited by Bodhidharma from his preceptor and it was handed down by Bhagvan Bodhidharma to his successor. In due course, Master Hung Zen being the fifth patriarch of the Zen community inherited it from his preceptor. And he is keen on handing it over to his successor if any. 

The narrative gradually thus seems to attain the heights of heroic poetry. In heroic poetry as such , a sword or a horse or a chariot seems to have  a personality of its own. Think of Gandiva –the bow of Arjuna in the Mahabharata. Think of the shield of Achilles in Homer . Here the begging  bowl and the robe become a person. 

In order that Hung Zen might choose his successor from his disciples , Master Hung Zen asked his disciples to write a poem on what they felt as wisdom. Thus, wisdom was the point in question.

Master Hung Zens exhortation to his disciples in this context is very important.He observed that performing good work or good conduct does not do away with the taints sticking to a person. Good work or good conduct only replaces bad taints with good ones. To take a parallel imagery from our daily life we could say that when we soap our body and then smear powder on it what we really do is to replace one kind of dust with another kind only. Hung Zen observed that morality has its limitation. Instead of being obsessed with morality Hung Zen observed one had better look into ones mind for wisdom and write. It must not be a labored one. One must write the way one understands wisdom—what wisdom is like.

Hung Zen’s announcement  fell flat on his disciples. There was one Shen Xiu who was deemed to be a very learned disciple of Master Hung Zen. Everybody thought Shen Xiu would compose the poem  and consequently he would be the next patriarch. And they would only obey Shen Xiu and follow him. 

This is no doubt an interesting episode.People donot commonly think on their own. Because they are satisfied having mugged the precepts of others. But to undertake a spiritual journey one must be a lamp unto himself.This was Bhagavan Buddhas  last sermon addressed to Master Ananda—attadipo bhava.Indeed we  men are reluctant to think on their own. This is why we fail even in the mundane world. Democracy ,for example, can only succeed when every one of us thinks on his own.

Shen Xiu  himself was however in a fix. To write or not to write the poem was his question. Maybe , he did not understand the reality. Why should he betray his ignorance? Everyone respected him . Why should he stake his popularity? But at the same time he wanted to know whether his understanding of the reality was right or not. Besides he asked himself whether he was keen on attaining the patriarchate. If that were the case he must not join in the competition. Because ambition stands in the way of spiritual development.   This vacillation humanizes the character of Shen Xiu. Finally he decided to write a stanza only to know whether his knowledge was superficial or deep according  to his master Master Hung Zen

 Hence, he pasted a poem on the wall of the monastery in secret. No one saw him to paste the poem. He did not put his name on the poem as its author. The poem was thus anonymous or written by an unknown author on the surface. 

The poem reads –

The body is the bodhi tree

The mind is the mirror bright

And one must see

No dust thereon alight

Master Hung Zen chanced upon the lines and at once he ordered his disciples to burn incense before them.

Later, Shen Xiu  visited the Master at the Masters bidding. The Master told   Shen Xiu  that Shen did not understand what the reality is. 

Master Hung Zen told Shen Xiu that one must know that there is a mind which is neither created nor annihilated. One who is always aware of it knows the  world as it is .

Shen Xiu  was very  dejected.

Thus the Zen masters behave in an unorthodox fashion. When a Zen master praises someone, the latter must be doubly cautious. May be one is praised by a Zen master only because one is in the wrong. 

The poem by Shen Xiu  was however widely popular among the inmates of the monastery . This was not surprising. Firstly Shen Xiu  was a senior inmate of the monastery. Secondly he was universally acknowledged as the learned man. Thirdly,patriarch Hung Zen outwardly showed respect to what Shen Xiu  had written. 

One day, Hui Neng heard an inmate of the monastery  recite the poem written by Shen Xiu  Hui Neng asked what it was. The former took pity on Hui Neng because Hui Neng did not know how to read or write . He helped Hui Neng to recite the poem. Later, Hui Neng went where the poem by Shen Xiu  was pasted upon the wall. When somebody read it out to him Hui Neng asked him to paste another poem on the wall. Hui Neng could not write, he dictated the poem. The poem was an instance of oral literature. The poem was pasted on the wall. Thus there were two poems vying with each other. 

So it reminds one of a tourney.There was Shen Xiu  alone flourishing at the tournament. There was no one to challenge him. After some time, a young man unknown and unsung came forward with his poem. The poem reads- 

There is no Bodhi tree

There is no mirror

Everything is void

And dust cannot alight anywhere

The event raised a stir among the inmates of the monastery. The patriarch Hung Zen saw the poem and read it. He then doffed his shoes and simply  erased Hui Nengs poem from the wall with his shoes. 

During the third watch of the night, Hung Zen went to Hui Neng secretly and stamped his staff in front of Hui Neng thrice and retired. Later during the third watch of the night, Hui Neng met Hung Zen in the latter’s chamber . There Hung Zen expounded the Diamond Sutra before Hui Neng and focused on the thought that said that one should use his mind as if it were free from attachment. At once Hui Neng was fully enlightened.

This is an interesting event. Earlier simply hearing the chant of the Diamond Sutra Hui Neng was enlightened.Despite that he went to Master Hung Zen because he being enlightened knew that he was not enlightened.Hung  Zen asked them write a stanza on mind off hand. Shen Xiu did not write off hand.He deliberated a lot before he pasted his poem . But unlettered though ,Hui Neng wrote that the void is all in all and void cannot be defiled. This came spontaneously from him. It was an instance of unpremeditated art.Here the source of knowledge was intuition. This episode shoots a sharp shaft of satire at modern education system. Literacy campaign among the masses only pays on the mundane level. Supramundane knowledge which sublates within it the mundane knowledge really comes from intuition. The mind must not be obsessed with secondary or derivative knowledge. True that Hui Neng wrote what came to him spontaneously. But he knew that he was yet to understand the mind.When Hung Zen visited Hui Neng while the latter was busy pounding rice Hung Zen asked==Is the rice ready? Hui Neng said---The rice needs to be sieved. Now during the third watch of the night at the instance of Bhagavan Hung Zen Hui Neng was fully enlightened. He knew the essence of the mind which alone is and which cannot be defiled. In short the rice was sieved.

The Zen masters do not trust language as the medium through which one could communicate wisdom. Wittgenstein , the philosopher of language had to admit that language could not give the whole truth. Hence he spoke of silence. And Zen teachers also made use of non verbal signs to direct the seekers to see the world as it is or the reality. 

One wonders why should Hui Neng meet his master Hung Zen during   the third watch of the night! Of course Hui Neng wanted to have conversation with Hui Neng in camera so that no  details of the same could transpire. But on another level the third watch reminds us of the third watch of the night when Lord Siddhartha Buddha understood how mind becomes attached and through attachment how men suffer.He also understood the possibility of deconditioning the attachment  and thereby attaining freedom

Lord Buddhas biography is heroic withal. True he did not conquer any mortal army on the battlefield.But he conquered Mara and his followers in battle array. Hung Zen in course of his conversation with Hui Neng observed that one who knows the mind is the hero , a Buudha.

Hung Zen gave away the begging  bowl an d the robe to Hui Neng and asked him to flee presently lest the supporters of Shen Xiu tortured him. Hui Neng said that he was from the South. He did not know the mountain roads in the area where the monastery was situated. Hung Zen himself led him along the roads in the locality. Finally they boarded on a boat. Hui Neng said that he would row . But Hung Zen said nay to his disciple. He himself rowed and steered the boat. This reminds one, of the preceptor as the ferryman who helps his disciple to cross the river of ignorance.

The preceptor left Hui Neng .  At the time of his parting Hung Zen said that Hui Neng must toil hard to liberate all sentient beings. But Hung Zen further added that the  practice of handing over the bowl and the robe to the successor should  be stopped henceforth. In other words Hui Neng was the last in the line of the Zen patriarchs to receive the bowl and the robe.

The relation between the preceptor Hung Zen and the disciple Hung Zen is curious. Here the transmission of the knowledge was from heart to heart. Hung Zen observed in his parting advice to Hui Neng that the enlightenment of the self could never reach its consummation unless one worked enlightenment for others. This implies bondless karuna or compassion for all things both great and small on the part of an enlightened being

  Hui Neng now left alone marched on .Southward ho!  He walked for two months and reached a hill. There he found hundreds of men had come to chase him.They wanted to rob him of the begging bowl and the robe. Among them there was one   Ming by name. Earlier he was an army general. He was very rough in his manners. Ming was about to overtake Hui  Neng . Hui Neng now saw that it was no use trying to escape from their approaching clutch. So what he did was to keep the robe and the begging bowl on a rock. He then told Ming that the robe and the begging bowl were just symbols . What use taking them by force?   Ming however proceeded to the rock just to lift up the robe and the begging bowl But lo! He could not lift them up. How come that they were too heavy for him. We guess he tried over and over again. But alas ! He could not move them an inch. In a moment there was a change in his attitude and character .He cried that he had come to His Holiness  Hui Neng not to rob him of his robe but to take lessons from him. Hui Neng now squatted before Ming and first thing that he exhorted was that Ming must not repent for his any activity whatever. Hui Neng asked Ming to refrain from any kind of thought whatever. Let the mind be blank. Ming performed that for a time.Hui Neng said that when the mind is really bereft of thought it is the self or the original face. At once Ming was enlightened

The episode is singularly important. How is that the robe and the begging bowl were too heavy for Ming? True that they were mere symbols. And yet they were too heavy for Ming. Does it not necessarily mean that symbols are not always mere symbols. They literally often point at the mysterium tremendum. In the language of semiology they are often indices. The robe and the begging bowl being too heavy for Ming pointed at the mysterium tremendum before which he was awestruck.He bowed before His Holiness Hui Neng and asked for instruction. And the only instruction that Hui Neng gave was to look into the mind as it is where there should be no thought,no repentance for the past no foreboding of the future. Any thought whatever is generated from forces acting upon the mind from without. Once these accidental qualities of mind are got rid of one is face to face with a vacuum in oneself.To know this is to be enlightened. Indeed the Dhammapada opens with

             Manopubbangamaa dhammaa

Ming took orders from Hui Neng and went away. One is at this point apt to think why Hung Zen asked Hui Neng to flee unnoticed from the monastery. On the surface it was out of fear that Hui Neng  should flee lest he was harmed by any one of the monastery jealous of Hui Neng. But on another level one wonders whether Hung Zen wanted that Hui Neng become a teacher on his own. Hung Zen said earlier that one must help oneself to get liberated. Similarly no one appoints one to be a teacher. A competent teacher can prove himself to be a teacher

Now that Ming went away Hui Neng resumed his journey. He found that he was still being pursued by evildoers. And now he joined hunter gatherers and lived with them for fifteen years incognito.Why did the enlightened one live with the huntergatherers for long fifteen years? This is a one lakh dollar question particularly in the modern context. There are hunter gatherers still in the world today. Some of them know the art of cultivation.But laugh at doing so. They point out that since Nature has enough to give to the hungry why should they cultivate. Anthropologists observe that they work for twelve hours or nineteen hours only a week to gather their fruits and they have as much calories as people from advanced countries do get. In a world overloaded with pollution we must go back to Nature and invoke Green Economics. We must live in Nature and live in harmony with Nature instead of compelling to adjust with our demands. So Master Hui Neng, it seems to us, lived with those men who lived on the bounty of Nature.

But after fifteen years he  came out of his seclusion impelled by his urge for teaching. One wonders why those huntergatherers who lived in Nature were not fit for the Masters prechings. Roland Barthes points out that there  are two kinds of texts. One is the  readerly text and the other is the writerly text. Like all great classics The Platform Sutra is a writerly text. There are gaps inwrought in a writerly text that provoke the readers to think on their own and fill up the gaps. May be the huntergatherers were not civilized enough to know what is good or bad. Those who know what is good or what is bad must be led out from the encircling delusion.

Hui Neng hence was about to enter a monastery . At the entrance itself two bhikkhus were deliberating on a flag that was fluttering. One of the bhikkhus said that it was the wind that moved the flag. The other said it was the flag that was moving on its own. The debate must not be taken lightly. We human beings do not know whether whatever we do or think  is our doing or thinking. Because everyone of us the product of the society. Our thoughts and manners are not our own , but impelled by our socialization. Because we are preys to circumstances. So the question whether the flag moves on its own or impelled by the wind  is a riddle still . Master Hui Neng however tells them that neither  the flag moves nor the wind moves. It is the mind that moves . Thus Master Hui Neng  decodes the riddle of the existence in terms of the mind. It naturally follows that there is a cosmic mind . And its motion or restlessness is behind the show of things that are ever in flux.

Master Hui Neng met the abbott of the monastery. The latter was impressed by his wisdom that transcended book learning.He guessed that it was Master Hui Neng the sixth patriarch of the Zen school. Master Hui Neng admitted that it was he. He told the abbott that Lord Buddhas teachings did not admit of more than  one way to liberation. The only way to liberation is to be aware of the essence of mind. Mind is neither eternal nor transitory . Hence it  is. Buddha Nature is. It is there in the heart of good men and badmen as well. Whoever looks into his own mind can discover the Buddha Nature for himself and be liberated . Even ichhantikas or the heretics can also discover Buddha Nature lurking in their hearts and get liberated.

Thus  Master Hui Neng gave all clarion call to everyone Buddhists or non Buddhists, good or evil , learned or illiterate , rich or poor to look into their hearts and find out the truths of the existence on their own. Every one must find the truth on his or her own.

The abbott of the monastery became a disciple of Master Hui Neng and Master Hui Neng henceforth appeared on the scene as a world teacher.

And he said at the end of the first chapter of his discourse that he was there at the lecture hall deliberating on truth and the path to liberation

The narrative as delineated in the first chapter of the Platform Sutra
thus comes full circle. It opened with Hui Neng  delivering a sermon.
It dwelled on how from a woodseller he became a patriarch giving
sermons.

The matrix of the society that functions as the background is
realistic. It is hierarchy ridden. The people of the South are looked
upon as barbarians. The illiterate are looked down upon.The educated
pity them. The illiterate are as it were meant for manual labour.They
cannot participate in  any higher conversation. But Buddha Nature
doesnot admit of any hierarchy. Buddha Nature is something that is
omnipresent and deathless. . Buddha Nature is all in all.
Enlightenment leaps from Buddha Nature only that lurks in every human
heart. Hence to attain enlightenment neither lot of studies of the
scriptures nor lot of penance is of any avail. Since Buddha Nature is
in every human heart every one can attain be he an icchantika or a
devoted Buddhist.

What is Buddha Nature? This  is a queer world  or samsara where we
live in . Here we sit by each other and hear each others groan. If
nirvana is  understood as the  opposite of the same, if It is bliss
only in relation with the samsara which is a vale of tears then
neither samsara is true nor nirvana.  Neither not-samsara is true nor
not-nirvana is true.Neither not not samsara is true nor not not
nirvana. Truth is neither not-samsara nor not nirvana. Buddha nature
is the truth. It is neither eternal nor not eternal..Hence it is the
void  which cannot be defiled and whence samsara and its antonym bliss
leaps forth.,One who knows the void or Buddha nature attains naiva
sanjnaa naasanjnaa..Enlightenment means neither consciousness nor not
consciousness, neither not not consciousness nor not not not
consciousness.

Tsen Xiu felt that Buddha Nature lurking in human heart must be kept
clean . Once Buddha Nature in man is befogged with dust he is plunged
into ignorance. But Hui Neng observed that Buddha Nature cannot be
defiled.Hence there is no point in becoming vigilant to keep Buddha
Nature free from pollution if any.Once one realizes Buddha Nature in
him one remains ever in the light of wisdom and enlightenment.
