Amrtab. Upanisad, 18, describes three modes of sitting-namely, the Lotus-seat (Padmasana), the sitting with legs bent underneath; the mystic diagram seat (Svastika); and the auspicious-seat (Bhadrasana);—while Yogacikha directs the choice of the Lotus-posture, with attention concentrated on the tip of the nose, hands and feet closely joined.
But Brahmanic Zen was carefully distinguished even by early Buddhists[FN#16] as the heterodox Zen from that taught by the Buddha. Our Zen originated in the Enlightenment of Shakya Muni, which took place in his thirtieth year, when he was sitting absorbed in profound meditation under the Bodhi Tree.
[FN#16] The anonymous author of Lankavatara-sutra distinguishes the heterodox Zen from the Hinayana Zen, the Hinayana Zen from the Mahayana Zen, and calls the last by the name of the Buddha's Holy Zen. The sutra is believed by many Buddhists, not without reason, to be the exposition of that Mahayana doctrine which Acvaghosa restated in his Craddhotpada-castra. The sutra was translated, first, into Chinese by Gunabbadra, in A.D. 443; secondly, by Bodhiruci in A.D. 513; and, thirdly, by Ciksanada in A.D. 700-704. The book is famous for its prophecy about Nagdrajuna, which (according to Dr. Nanjo's translation) is as follows:
"After the Nirvana of the Tathagata,
There will be a man in the future,
Listen to me carefully, O Mahatma,
A man who will hold my law.
In the great country of South,
There will be a venerable Bhiksu
The Bodhisattva Nagarjuna by name,
Who will destroy the views of Astikas and Nastikas,
Who will preach unto men my Yana,
The highest Law of the Mahayana,
And will attain to the Pramudita-bhumi."
It is said that then he awoke to the perfect truth and declared: "All animated and inanimate beings are Enlightened at the same time." According to the tradition[FN#17] of this sect Shakya Muni transmitted his mysterious doctrine from mind to mind to his oldest disciple Mahakacyapa at the assembly hold on the Mount of Holy Vulture, and the latter was acknowledged as the first patriarch, who, in turn, transmitted the doctrine to Ananda, the second patriarch, and so till Bodhidharma, the twenty-eighth[FN#18] patriarch. We have little to say about the historical value of this tradition, but it is worth while to note that the list of the names of these twenty-eight patriarchs contains many eminent scholars of Mahayanism, or the later developed school of Buddhism, such as Acvaghosa,[FN#19] Nagarjuna,[FN#20] Kanadeva,[FN#21] and Vasubhandhu.[FN#22]
[FN#17] The incident is related as follows: When the Buddha was at the assembly on the Mount of Holy Vulture, there came a Brahmaraja who offered the Teacher a golden flower, and asked him to preach the Dharma. The Buddha took the flower and held it aloft in his hand, gazing at it in perfect silence. None in the assembly could understand what he meant, except the venerable Mahakacyapa, who smiled at the Teacher. Then the Buddha said: "I have the Eye and Treasury of Good Dharma, Nirvana, the Wonderful Spirit, which I now hand over to Mahakacyapa." The book in which this incident is described is entitled 'Sutra on the Great Brahman King's Questioning Buddha to Dispel a Doubt,' but there exists no original text nor any Chinese translation in the Tripitaka. It is highly probable that some early Chinese Zen scholar of the Sung dynasty (A.D. 960-1126) fabricated the tradition, because Wang Ngan Shih (O-an-seki), a powerful Minister under the Emperor Shan Tsung (Shin-so, A.D. 1068-1085), is said to have seen the book in the Imperial Library. There is, however, no evidence, as far as we know, pointing to the existence of the Sutra in China. In Japan there exists, in a form of manuscript, two different translations of that book, kept in secret veneration by some Zen masters, which have been proved to be fictitious by the present writer after his close examination of the contents. See the Appendix to his Zen-gaku-hi-han-ron.
[FN#18] The following is the list of the names of the twenty-eight patriarchs:
1. Mahakacyapa. 2. Ananda. 3. Canavasu. 4. Upagupta. 5. Dhrtaka. 6. Micchaka. 7. Vasumitra. 8. Buddhanandi. 9. Buddhamitra. 10. Parcva. 11. Punyayacas. 12. Acvaghosa. 13. Kapimala. 14. Nagarjuna. 15. Kanadeva. 16. Rahulata. 17. Samghanandi. 18. Samghayacas. 19. Kumarata. 20. Jayata. 21. Vasubandhu. 22. Manura. 23. Haklanayacas. 24. Simha. 25. Vacasuta. 26. Punyamitra. 27. Prajnyatara. 28. Bodhidharma.
The first twenty-three patriarchs are exactly the same as those given in 'The Sutra on the Nidana of transmitting Dharmapitaka,' translated in A.D. 472. King Teh Chwen Tang Iuh (Kei-toku-den-to-roku), a famous Zen history of China, gives two elaborate narratives about the transmission of Right Dharma from teacher to disciple through these twenty-eight patriarchs, to be trusted without hesitation. It would not be difficult for any scholar of sense to find these statements were made from the same motive as that of the anonymous author who gives a short life, in Dirghagama-sutra, of each of the six Buddhas, the predecessors of Shakya Muni, if he carefully compare the list given above with the lists of the patriarchs of the Sarvastivada school given by San Yin (So-yu died A.D. 518) in his Chuh San Tsung Ki (Shutsu-san zo-ki).
[FN#19] One of the founders of Mahayana Buddhism, who flourished in the first century A.D. There exists a life of his translated into Chinese by Kumarajiva in A.D. 401-409. The most important of his works are: Mahayanacraddhotpada-castra, Mahalankara-sutra-castra, Buddha-caritakavya.
