1. IMPORTANCE OF THE DOCTRINE
The doctrine of Paticcasamuppadaor Dependent Origination is very important in Buddhism. The bodhisatta began with dependent origination when he reflected deeply on the nature of existence and attained Enlightenment. He first pondered old age and death as did every other bodhisatta when he was about to become the Buddha in his last existence. For it was only after seeing the old, the sick and the dead that the bodhisatta saw the ascetic (samana) and renounced the world in search of the ageless and the deathless Dhamma. He had seen the evils of life in old age, sickness and death.
Every living being wants to avoid these evils of life but there is no end to these evils which follow him in one existence after another. In view of this endless process of life all living beings appear to be in bondage and subject to suffering. Life is in fact an infinite process of births and deaths. The fate of fowls and ducks is terrible indeed. Some are eaten up while still in the eggs. If they emerge from the eggs they do not live long but are killed when they grow up a little. They are born only to be killed for human consumption. If the fate of a living being is thus to be repeatedly killed it is gloomy and frightful indeed.
But the fowls and ducks appear to be well content with their lot in life. They apparently enjoy life, quacking, crowing, eating and fighting with one another. They may think that they have a lot of time to live although in fact they have little time to be happy, their life being a matter of days or months, with each of them coming into existence and then dying after a short time.
The span of human life, too, is not very long. For the man in his fifties or sixties the past seems in retrospect as recent as yesterday. Sixty or seventy years on earth is a day in the life of a deva which is. however, very short in the eyes of a Brahma who may live as long as the duration of the worlds (kappa). But even the Brahma who outlives hundreds of worlds is insignificant and his life is short in the context of samsaric eternity. Devas and Brahmas, too, have to age and die eventually. Although they are not subject to sickness and marked dotage, age tells on them invisibly in due course of time. So every living being has to face old age and death and nobody can escape from these evils of life.
2. REFLECTION OF THE BODHISATTA
Reflecting on the origin of old age, the bodhi satta traced back the chain of dependent origination from the end to the beginning. Old age and death have their origin in rebirth which in turn is due to kammabhava (condition or kamma for renewed existence). kammabhava stems from grasping or attachment (upadana) which is caused by craving (tanha). Craving arises from feeling (vedana) which is produced by sense—bases (ayatana) such as eye, visual form, etc. Sense—bases are the product of nama rupa (consciousness and corporeality) which results from vinnana (consciousness) which is again caused by nama rupa.
The full Pali texts about Paticcasamuppada attribute vinnana to sankhra (kamma-formations) and sankhra to avijja (ignorance). But the bodhisatta's reflection is confined to the interdependence of nama rupaand vinnana in the present life. In other words, he reflected on the correlation between vinnana and nama rupaleaving out of account the former's relation to past existence. We may assume therefore that for the yogis reflection on the present life will suffice to ensure the successful practice of vipassana.
3. ANULOMA REASONING
The bodhisatta reasoned about the correlation between vinnana and nama-rupa thus: "This vinnana has no cause other than nama-rupa From nama-rupa there results vinnana from vinnana there arises nama-rupa Hence from the correlation between vinnana and nama-rupa there arise birth, old age and death; there may be successive births or successive deaths."
Moreover vinnana causes nama-rupa ; nama-rupa causes sense-bases (ayatana). From sense-bases there arises contact; contact leads to feeling, feeling gives rise to craving, craving to grasping, and grasping results in rebirth which in turn leads to old age, death, anxiety, grief and other kinds of mental and physical suffering.
Then the bodhisatta reflected on dependent origination negatively. If there were no vinnana there could be no nama-rupa; if no nama-rupa, then no ayatana and so on. The negation of the first link in the chain of causation leads to the extinction of suffering that has beset us ceaselessly in the infinite series of samsaric existences. After this reflection on dependent origination in its positive and negative aspects, the bodhi satta contemplated the nature of the aggregates of grasping. Then he attained the successive insights and fruitions (maggaphala) on the Ariyan holy path and finally became the all-Enlightened Buddha. Every bodhisatta attained supreme Enlightenment after such contemplation. They did not learn what and how to contemplate from others but owing to cumulative potential (parami) that they had acquired through innumerable lifetimes, they contemplated as mentioned before and attained Enlightenment.
4. BEYOND REASONING AND SPECULATION
Then when it was time to preach the Buddha thought thus: This dhamma which I know is very profound. It is hard to understand; it is so sublime and so conducive to inner peace. It is not accessible to intellect and logic (atakkavacaro). It is subtle and it is to be realized only by the wise.
All over the world philosophers have racked their brains about freedom from old age, sickness and death. But freedom from these evils means Nibbana and Nibbana is beyond the reach of reason and intellect. It is to be realized only through the practice of the middle way and vipassana. Most philosophers rely on intellect and logic and there are various doctrines which they have conceived for the welfare of all living beings. But these doctrines are based on speculations that do not help anyone to attain vipassana insight, let alone the supreme goal of Nibbana. Even the lowest stage of vipassana insight, viz,, insight into the distinction between nama and rupa does not admit of intellectual approach. The insight dawns on the yogi only when, with the development of concentration, and in accordance with Satipatthana method he watches the nama-rupa process and distinguishes between consciousness and corporeality, e.g. the desire to bend the hand and bent hand, the ear and the sound on the one hand and the consciousness of hearing on the other and so forth. Such know ledge is not vague and speculative; it is vivid and empirical.
It is said on the authority of scriptures that nama-rupas are in a constant flux and that we should watch their arising and passing away. But for the beginner this is easier said than done. The beginner has to exert strenuous effort to overcome hindrances (nivarana). Even freedom from nivarana helps him only to distinguish between nama and rupa. It does not ensure insight into their arising and passing away. This insight is attained only after concentration has been developed and perception has become keen with the practice of mindfulness. Constant mindfulness of arising and vanishing leads to insight into anicca, dukkha and anatta of all phenomena. But as merely the beginning of lower vipassana, this insight is a far cry from the path and its fruition. Hence the description of the dhamma as something beyond logic and speculation.
5. DHAMMA IS ONLY FOR THE WISE
The dhamma is subtle (nipuno); it is to be realized only by the wise (Panditavedaniyo) Here the wise means only those who have wisdom (panna) relating to vipassana and the path and its goal. The dhamma has nothing to do with the secular knowledge per se possessed by world philosophers, religious founders, writers or great scientists who can split atoms. But it can be realized by any one irrespective of sex, age or education, anyone who contemplates nama-rupa at the moment of their arising, passes through vipassana insights progressively and attains the Ariyan path and its goal.
Taking stock of the nature of all living beings, the Buddha found that most of them were mired in sensual pleasure. There were of course a few exceptions like the five companions of Siddhattha in the forest retreat or the two brahmins who were later to become the two chief disciples of the Buddha. But the majority of mankind regard the enjoyment of pleasure as the summum bonum of life. They are like children who delight in playing with their toys the whole day. The child's toys and games make no sense to adults but grown—up people too derive pleasure from the toys of the sensual world, that is, from the company of their children and grand children. Such sensual pleasure has no appeal for Buddhas and Arahats. It is highly esteemed by ordinary men and devas because they have no sense of higher values such as jhana, vipassana and Nibbana.
A person who is thus fond of sensual pleasure may be likened to a peasant living in out-of-the-way rural areas. To the urbanites those places are wholly devoid of the amenities of life, what with poor food, poor clothes, dirty dwellings, muddy foot-paths and so forth. But the villagers are happy and they never think of leaving their native place. Likewise, common people and devas delight in their sensual objects. Whatever the teaching of the Buddha and the Arahats, they love pleasure and spend all their time indulging in it. They feel ill at ease in the absence of sensual objects. They are so much pleased with their families, attendants and possessions that they cannot think of anything higher than sensual pleasure. Because of their deep-rooted love of pleasure, it is hard for them to understand or appreciate the subtle, profound Paticcasamuppada and Nibbana.
6. Difficulty of Understanding
The Buddha-dhamma makes little appeal to the masses since it is diametrically opposed to their sensual desire. People do not like even an ordinary sermon, let alone a discourse on Nibbana, if it has no sensual touch. They do not seem interested in our teaching and no wonder, since it is devoid of melodious recitation sentimental stories and hilarious jokes and other attractions. It is acceptable only to those who have practised vipassana or who seek the dhamma on which they can rely for methods of meditation and extinction of defilements.
But it is a mistake to deprecate, as sone do, the sermons containing stories, jokes, etc as sutta sermons. Suttas differ basically from popular sermons in that they are profound, as witness Anattalakkhana sutta , Satipatthana sutta and so forth. The doctrine of Dependent Origination too belongs to Sutta Pitaka. It is to be labelled Abhidhamma only because it is preached in the fashion of Abhidhamma Pitaka.
Since our teaching is unadulterated dhamma, some people confuse it with Abhidhamma and cannot follow it, much less grasp the Path and Nibbana which it emphasizes. Paticcasamuppada is hard to understand because it concerns the correlations between causes and effects. There is no ego entity that exists independently of the law of causation. It was hard to accept this fact before the Buddha proclaimed the dhamma.
The commentaries also points out the abstruse character of the doctrine. According to them there are four dhammas which defy understanding, viz., the four noble truths, the nature of a living being, the nature of rebirth and dependent origination.
It is hard to understand and accept the truth of suffering, the truth about its cause, the truth about its cessation and the truth about the way to its extinction. It is hard to appreciate these truths, still harder to teach them to other people.
Secondly, it is hard to understand that a living being is a nama-rupa process without any separate self, that the complex is subject to the law of kamma that determines a man's future life according to his good or bad deeds.
In the third place, it is hard to see how rebirth takes place as a result of defilement and kamma without the transfer of nama-rupa from a previous life.
Lastly it is equally hard to understand Paticcasamupada. It involves the above three abstruse dhammas. Its negative aspect concerns the first two noble truths as well as the nature of a living being and rebirth while its positive aspect involves the other two truths. Hence it is most difficult to grasp or teach this doctrine. It may be easy to explain it to one who has attained the path and Nibbana or one who has studied the Pitaka but it will mean utile to one who has neither the illumination nor scriptural knowledge.
The writer of the commentary on the doctrine was qualified to explain it because he might have attained the lower stages of the path or he might have a thorough knowledge of the Pitaka. He refers to its difficulty probably in order that its exposition might be seriously studied by posterity. He likens the difficulty to the plight of a man who has jumped into the sea and cannot get to the bottom. He admits that he has written the exegesis on the basis of the Pitaka and the old commentaries handed down by oral tradition. The same may be said of our teaching. Since it is hard to explain the doctrine, the yogi should pay special attention to it if he follows the teaching superficially, he will understand nothing and without a fair knowledge of the doctrine, he is bound to suffer in the wilderness of samsaric existence.
The substance of the Paticcasamuppada teaching is as follows.
From ignorance there arises sankhara (effort or kamma-formation). From kamma-formation there arises consciousness of the new existence. Consciousness gives rise to psycho-physical phenomena or nama-rupa. Nama-rupa leads to ayatana (six bases). From ayatana arises the phassa (impression). Phassa causes feeling; feeling leads to craving. From craving there results clinging (Upadana). Because of clinging there is the process of becoming (kamma-bhava), from the process of becoming there arises rebirth (jati) and rebirth leads to old age, death, sorrow grief, and lamentation. Thus arises the whole mass of suffering.
7. WHAT IS avijja (IGNORANCE)?
According to the Buddha, avijja is ignorance of the four Noble Truths, viz., the truths about suffering, its cause, its cessation and the way to its cessation. In a positive sense avijja implies misconception or illusion. It makes us mistake what is false and illusory for truth and reality. It leads us astray and so it is labelled micchapatipatti-avijja.
Avijja therefore differs from ordinary ignorance. Ignorance of the name of a man or a village does not necessarily mean misinformation whereas the avijja of Paticcasamuppada means something more than ignorance. It is misleading like the ignorance of a man who has lost all sense of direction and who therefore thinks that the east is west or that the north is south. The man who does not know the truth of suffering has an optimistic view of life that is full of dukkha (pain and evil).
It is a mistake to seek the truth of dukkha in the book for it is to be found in one's own body. Seeing, hearing, in short, all nama-rupa arising from the six senses are dukkha For this phenomenal existence is impermanent, undesirable and unpleasant. It may end at any time and so all is pain and suffering. But this dukkha is not realized by living beings who look upon their existence as blissful and good.
So they seek pleasant sense-objects, good sights, good sounds, good food, etc. Their effort to secure what they believe to be the good things of life is due to their illusion (avijja) about their existence. Avijja is here like the green eye-glass that makes a horse eat the dry grass which it mistakes for green grass. Living beings are mired in sensual pleasure because they see every thing through rose-coloured glasses. They harbour illusions about the nature of sense-objects and nama-rupa.
A blind man may be easily deceived by another man who offers him a worthless longyi, saying that it is an expensive, high quality longyi. The blind man will believe him and he will like the longyi very much. He will be disillusioned only when he recovers his sight and then he will throw it away at once. Likewise, as a victim of avijja, a man enjoys life, being blind to its anicca, dukkha and anatta. He becomes disenchanted when introspection of nama-rupa makes him aware of the unwholesome nature of his existence.
Introspection of nama-rupa or vipassana contemplation has nothing to do with bookish knowledge. It means thorough watching and ceaseless contemplation of all psycho-physical phenomena that comprise both the sense-objects and the corresponding consciousness. The practice leads to full awareness of their nature. As concentration develops, the yogi realizes their arising and instant vanishing, thereby gaining an insight into their anicca, dukkha and anatta.
Avijja makes us blind to reality because we are unmindful. Unmindfulness gives rise to the illusion of man, woman, hand, leg, etc., in the conventional sense of the terms. We do not know that seeing, for instance, is merely the nama-rupa or psychophysical process, that the phenomenon arises and vanishes, that it is impermanent, unsatisfactory and unsubstantial.
Some people who never contemplate die without knowing anything about nama-rupa The real nature of nama-rupa process is realized by the mindful person. But the insight does not occur in the beginning when concentration is not yet developed. Illusion or the natural way of consciousness precedes contemplation and so the beginner does not gain a clear insight into the nature of nama-rupa It is only through steadfast practice that concentration and perception develop and lead to insight- knowledge.
If, for example, while practising mindfulness, the yogi feels itchy, he is barely aware of being itchy. He does not think of the hand, the leg, or any other part of the body that is itchy nor does the idea of self as the subject of itchiness, "I feel itchy's occur to him. There arises only the continuous sensation of itchiness. The sensation does not remain permanent but passes away as he notes it. The watching consciousness promptly notes every psychophysical phenomenon, leaving no room for the illusion of hand, leg and so on.
Illusion dominates the unmindful person and makes him blind to the unsatisfactory nature dukkha of all sense-objects. It replaces dukkha with sukha. Indeed avijja means both ignorance of what is real and misconception that distorts reality.
Because he does not know the truth of dukkha man seeks pleasant sense-objects. Thus ignorance leads to effort and activity (sankhara) According to the scriptures, because of avijja there arises sankhara but there are two links, viz., tanha and upadana between them. Ignorance gives rise to craving (tanha ) which later on develops into attachment (upadana). Craving and attachment stem from the desire for pleasure and are explicitly mentioned in the middle part of the doctrine of Paticcasamuppada. When the past is fully described, reference is made to avijja , tanha , upadana, kamma and sankhara.
