The author of the Wei-lüeh comments on the resemblance of Buddhist writings to the work of Lao-tzŭ, and suggests that the latter left China in order to teach in India. This theory found many advocates among the Taoists, but is not likely to commend itself to European scholars. Less improbable is a view held by many Chinese critics[602] and apparently first mentioned in the Sui annals, namely, that Buddhism was introduced into China at an early date but was exterminated by the Emperor Shih Huang Ti (221-206) in the course of his crusade against literature. But this view is not supported by any details and is open to the general objection that intercourse between China and India _viâ_ Central Asia before 200 B.C. is not only unproved but improbable.
Still the mystical, quietist philosophy of Lao-tzŭ and Chuang-tzŭ has an undoubted resemblance to Indian thought. No one who is familiar with the Upanishads can read the Tao-Tê-Ching without feeling that if Brahman is substituted for Tao the whole would be intelligible to a Hindu. Its doctrine is not specifically Buddhist, yet it contains passages which sound like echoes of the Pitakas. Compare Tao-Tê-Ching, 33. 1, "He who overcomes others is strong: he who overcomes himself is mighty," with Dhammapada, 103, "If one man overcome a thousand thousand in battle and another overcome himself, this last is the greatest of conquerors"; and 46. 2, "There is no greater sin that to look on what moves desire: there is no greater evil than discontent: there is no greater disaster than covetousness," with Dhammapada, 251, "There is no fire like desire, there is no monster like hatred, there is no snare like folly, there is no torrent like covetousness." And if it be objected that these are the coincidences of obvious ethics, I would call attention to 39. 1̣, "Hence if we enumerate separately each part that goes to form a cart, we have no cart at all." Here the thought and its illustration cannot be called obvious and the resemblance to well-known passages in the Samyutta Nikâya and Questions of Milinda[603] is striking.
Any discussion of the indebtedness of the Tao-Tê-Ching to India is too complicated for insertion here since it involves the question of its date or the date of particular passages, if we reject the hypothesis that the work as we have it was composed by Lao-tzŭ in the sixth century B.C.[604] But there is less reason to doubt the genuineness of the essays of Chuang-tzŭ who lived in the fourth century B.C. In them we find mention of trances which give superhuman wisdom and lead to union with the all-pervading spirit, and of magical powers enjoyed by sages, similar to the Indian _iddhi_. He approves the practice of abandoning the world and enunciates the doctrines of evolution and reincarnation. He knows, as does also the Tao-Tê-Ching, methods of regulating the breathing which are conducive to mental culture and long life. He speaks of the six faculties of perception, which recall the Shaḍâyatana, and of name and real existence (nâmarûpam) as being the conditions of a thing[605]. He has also a remarkable comparison of death to the extinction of a fire: "what we can point to are the faggots that have been consumed: but the fire is transmitted and we know not that it is over and ended." Several Buddhist parallels to this might be cited[606].
