When we compare Zen as a finished product to the Doctrine of Enlightenment as the latter began to unfold itself in primitive Buddhism, we find a wide and seemingly impassable gap between the two. This was however naturally to be expected. Let us consider the following facts. In the beginning, the Buddha was somewhat timid to disclose the entire secrets of the reason of Buddhahood, thinking that his disciples were not quite capable of following every step he had taken himself. The feeling he first had after Enlightenment governed him almost throughout the entire course of his earthly life. It was this, that the Perfect Supreme Enlightenment attained by him was too exalted an object for sentient beings to strive after, and that even when it were disclosed to them they would not fully comprehend it but might defile it to their own demerit. Did he not even think of passing into Nirvana right after Enlightenment? His whole life, in spite of the advice of the Brahmadeva, seems to have been controlled by this feeling—the reluctance to reveal the entirety of his inmost self-realisation (pratyātmajñāna, according to the terminology of the Laṅkāvatāra). In point of fact, the Buddha himself might have communicated what he realised to all his disciples unreservedly, but the impression we get from the Agama or Nikaya literature is that he was actually reluctant to do so. At least this was the way the earlier writers of the canonical books attempted to represent their master whatever their motives might be. This being the case, the idea of Enlightenment was not brought forward so fully and conspicuously in Hinayana literature as at once to command our attention. But as I pointed out, this idea lies only superficially buried among the other and less important ideas, and can easily be made manifest by logically and psychologically following up the course of events related in the canonical writings concerning the Enlightenment of the Buddha.

The earlier writers conceived the Fourfold Noble Truth or the Twelvefold Chain of Causation, or the Eightfold Path of Righteousness to be the central teaching of Buddhism, which also included on the psychological side the theory of non-ego (anātman). But when we reflect, both philosophically and from the Zen point of view, on the life of the Buddha and on the ultimate principle of Buddhahood, we cannot help thinking of his Enlightenment as the most significant and most essential and most fruitful part of Buddhism. Therefore, what the Buddha really wished to impart to his disciples must be said to have been the Doctrine of Enlightenment in spite of the Hinayanistic interpretation or understanding of what is known as primitive Buddhism. But as long as Buddhism flourished in India, this its central idea remained what it was, that is, such as is developed in most of the Mahayana Sutras. It was only after Bodhi-Dharma who brought it to China that the idea took root there and grew up to what we designate now specifically as the Zen school of Buddhism. The history of Zen, therefore, properly speaking or in its narrower sense, may best be regarded as beginning in China. The Indian soil was too metaphysical, too rich in romantic imagination for Zen to grow as such in its pure form.

While the attainment of Buddhahood or Arhatship was the ultimate goal of his teaching, the Buddha was practical and always close to the facts of life and insisted in his ordinary sermons on a life regulated by moral rules. Nor had he any desire to disclose intellectually or metaphysically the content of Enlightenment which must be experienced but cannot be explained. He never neglected to emphasise the significance of self-realisation, for Nirvana or Enlightenment was to be attained personally through one’s own efforts in one’s own inner consciousness. The Fourfold Noble Truth or the Twelvefold Chain of Causation or the Theory of Non-ego was an intellectual guide to the realisation of the Buddhist life. Such teaching could not have any practical meaning except as finally leading to Enlightenment. The Buddha never thought that his followers would come to lay the entire stress of his teaching on these intellectual structures which could not stand by themselves without being supported by an inner spirit. The Eightfold Path of Righteousness was an ethical guide to Enlightenment, and as such it was regarded by the Buddha. Those who have no higher insight into his teaching than reading a moral signification in it, take it for a kind of ethical culture and no more. They think that Buddhism is a positivism as philosophy and its Brotherhood (saṁgha) a body of moral ascetics. They praise the Buddha as the originator of a scientific religious system free from spiritualistic superstitions which so frequently and abundantly grow around religion. But we know better because these comments are not in full accord with the teaching of the Buddha, for they only reflect one side of it and fail to take an inner and comprehensive view of the whole field. If these critics took up the practise of dhyana as constituting the essence of Buddhism along with the above considerations, they may be said to have come nearer to the goal; but even this dhyana is a form of spiritual exercise which will prepare the way to the final realisation of Nirvana. Dhyana in itself does not distinguish Buddhism from the other philosophico-religious systems which existed in India in the day of the Buddha. Therefore, to understand Zen as expressing the Doctrine of Enlightenment which is the reason of Buddhism, we must wait for the rise of the Mahayana movements. And when this was introduced into China by Bodhi-Dharma, it grew up to what we now know by the name of Zen Buddhism.

The legendary story of the origin of Zen in India runs as follows: Śākyamuni was once engaged at the Mount of the Holy Vulture in preaching to a congregation of his disciples. He did not resort to any lengthy verbal discourse to explain his point, but simply lifted a bouquet of flowers before the assemblage, which was presented to him by one of his lay-disciples. Not a word came out of his mouth. Nobody understood the meaning of this except the old venerable Mahākāśyapa, who quietly smiled at the Master, as if he fully comprehended the purport of this silent but eloquent teaching on the part of the Enlightened One. The latter perceiving this opened his golden-tongued mouth and proclaimed solemnly: “I have the most precious treasure, spiritual and transcendental, which this moment I hand over to you, O venerable Mahākāśyapa!”[4.1]

Orthodox Zen followers generally blindly take this incident to be the origin of their doctrine, in which, according to them, is disclosed the inmost mind of the Buddha as well as the secret of the religion. As Zen claims to be the inmost essence of Buddhism and to have been directly transmitted by the Buddha to his greatest disciple, Mahākāśyapa, its followers naturally look for the particular occasion when this transmission took place between the master and the disciple. We know in a general way that Mahākāśyapa succeeded the Buddha as the leader of the Faith, but as to his special transmission of Zen, we have no historical records in the Indian Buddhist writings at present in our possession. This fact is however specially mentioned for the first time as far as we know in a Chinese Zen history called The Records of the Spread of the Lamp,[4.2] compiled by Li Tsun-hsü, in 1029, and also in The Accounts of the Orthodox Transmission of the Dharma compiled by Ch‘i-sung in 1064,[4.3] where this incident is only referred to as not quite an authentic one historically. In The Records of the Transmission of the Lamp,[4.4] written in 1004, which is the earliest Zen history now extant, the author does not record any particular event in the life of the Buddha regarding the Zen transmission. As all the earlier histories of Zen are lost, we have at present no means to ascertain how early the Zen tradition started in China. Probably it began to be talked about among the Zen followers when their religion had been well established in China late in the eighth century.

In those days there must have been some necessity to invent such a legend for the authorisation of Zen Buddhism; for as Zen grew in strength the other schools of Buddhism already in existence grew jealous of its popular influence and attacked it as having no authorised records of its direct transmission from the founder of Buddhism, which was claimed by the devotees of Zen. This was the case especially when the latter made so light of the doctrinal teaching discussed in the Sutras and Śastras, as they thought that the ultimate authority of Zen issued out of their own direct personal experience. In this latter they were quite insistent; but they were not, nor could they be, so critical and independent as to ignore altogether the authority of historical Buddhism, and they wanted somehow to find the record that the Buddha handed Zen over to Mahākāśyapa and from Mahākāśyapa on to the twenty-eighth patriarch, Bodhi-Dharma, who became the first patriarch of Zen in China. A line of twenty-eight Indian patriarchs thus came to be established by Zen historians, while, according to other schools, there were only twenty-three or twenty-four patriarchs after the founder. When the historians had the need for the special transmission of Zen from the Buddha to Mahākāśyapa, they felt it necessary to fill up the gap between the twenty-third or twenty-fourth patriarch and Bodhi-Dharma himself, who according to them was the twenty-eighth. From the modern critical point of view, it did not matter very much whether Zen originated with Bodhi-Dharma in China or with the Buddha in India, inasmuch as Zen is true and has an enduring value. And again from the historian’s point of view which tries scientifically to ascertain the source of development resulting in Zen Buddhism, it is only important to find a logical connection between the Mahayana Doctrine of Enlightenment in India and its practical application by the Chinese to the actualities of life; and as to any special line of transmission in India before Bodhi-Dharma as was established by the Zen devotees, it is not a matter of much concern nor of great importance. But as soon as Zen is formulated into an independent system, not only with its characteristic features but with its historically ascertainable facts, it will be necessary for the historians to trace its line of transmission complete and not interrupted; for in Zen, as we shall see later, it is of the utmost importance for its followers to be duly certified or approved (abbhanumodana) by the master as to the genuineness or orthodox character of their realisation. Therefore, as long as Zen is the product of the Chinese soil from the Indian seed of Enlightenment as I take it, no special line of transmission need be established in India unless it is in a general logical manner such as was attempted in my previous Essays.

The twenty-eight patriarchs of Zen regarded by its followers as the orthodox line of transmission are as follows:

  1. Śākyamuni.
  2. Mahākāśyapa.
  3. Ānanda.
  4. Śaṇavāsa.
  5. Upagupta.
  6. Dhṛitaka.
  7. Micchaka.
  8. Buddhanandi.
  9. Buddhamitra.
  10. Bhikshu Parśva.
  11. Puṇyayaśas.
  12. Aśvaghosha.
  13. Bhikshu Kapimala.
  14. Nāgārjuna.
  15. Kāṇadeva.
  16. Ārya Rāhulata.
  17. Saṁghanandi.
  18. Saṁghayaśas.
  19. Kumārata.
  20. Jayata.
  21. Vasubandhu.
  22. Manura.
  23. Haklenayaśas.
  24. Bhikshu Siṁha.
  25. Vāśasita.
  26. Puṇyamitra.
  27. Prajñātara.
  28. Bodhi-Dharma.

To be consistent with the view that Zen was a “special transmission from the Buddha outside of his doctrinal teaching,” Zen historians have extended this transmission even beyond Śākyamuni; for, according to tradition prevalent already among primitive Buddhists, there were at least six Buddhas prior to the Buddha of the present kalpa who was the Muni of the Śākyas; and these several Buddhas had each to leave a gāthā of “Dharma transmission” which is systematically preserved in Zen history. Now if the six Buddhas of the past had their gāthās, why not those patriarchs between Śākyamuni and Bodhi-Dharma, all inclusively? Or, if any one of them had at all any kind of gāthā, why not the rest of them too? So, they have all bequeathed their gāthās of transmission regularly prefaced with the words: “I now hand over to you the eye-treasure of the Great Law, which you will guard and ever be mindful of.” No doubt they are fictitious productions of the historical imagination which was so highly exercised by the early writers of Zen history, evidently inspired by an extraordinary zeal for their orthodox faith.
