But though coins and sculpture bring clearly before us a medley of deities corresponding to a medley of human races, they do not help us much in tracing the growth of thought, phases of which are preserved in a literature sufficiently copious though the record sometimes fails at the points of transition where it would be of most interest. It is natural that sacred books should record accepted results rather than tentative innovations and even disguise the latter. But we can fix a few dates which enable us to judge what shape Buddhism was taking about the time of the Christian era. The Tibetan historian Târanâtha is not of much help, for his chronology is most confused, but still he definitely connects the appearance of Mahayanist texts with the reign of Kanishka and the period immediately following it178 and regards them as a new phenomenon. Greater assistance is furnished by the Chinese translators, whose dates are known with some exactitude. Thus the earliest Buddhist work rendered into Chinese is said to be the sutra of forty-two sections, translated by Kâśyapa Mâtanga in 67 A.D. It consists of extracts or resumés of the Buddha's teaching mostly prefaced by the words "The Buddha said," doubtless in imitation of the Confucian Analects where the introductory formula "The master said" plays a similar part. Its ideas and precepts are Hinayanist:179 the Arhat is held up as the ideal and in a remarkable passage180 where the degrees of sanctity are graded and compared no mention is made of Bodhisattvas. This first translation was followed by a long series of others, principally from the Sûtra-Piṭaka, for very little of the Vinaya was translated before the fifth century. A great number of Hinayanist sutras were translated before 300 A.D. but very few after 450. On the other hand portions of the sutra about Amîda's Paradise, of the Prajñâ-pâramitâ, and of the Avataṃsaka were translated about 150 A.D. and translations of the Lotus and Lalita-vistara appeared about 300.
Great caution is necessary in using these data and the circumstances of China as well as of India must be taken into account. If translations of the Vinaya and complete collections of sutras are late in appearing, it does not follow that the corresponding Indian texts are late, for the need of the Vinaya was not felt until monasteries began to spring up. Most of the translations made before the fifth century are extracts and of indifferent workmanship. Some are retained in the Chinese Tripitaka but are superseded by later versions. But however inaccurate and incomplete these older translations may be, if any of them can be identified with a part of an extant Sanskrit work it follows that at least that part of the work and the doctrines contained in it were current in India or Central Asia some time before the translation was made. Applying this principle we may conclude that the Hinayana and Mahayana were flourishing side by side in India and Central Asia in the first century A.D. and that the Happy Land sutras and portions of the Prajñâ-pâramitâ already existed. From that time onwards Mahayanist literature as represented by Chinese translations steadily increases, and after 400 A.D. Hinayanist literature declines, with two exceptions, the Vinaya and the Abhidharma books of the Sarvâstivâdins. The Vinaya was evidently regarded as a rule of life independent of theology, but it is remarkable that Hsüan Chuang after his return from India in 645 should have thought it worth while to translate the philosophy of the Sarvâstivâdins.
Other considerations render this chronology probable. Two conspicuous features of the Mahayana are the worship of Bodhisattvas and idealist philosophy. These are obviously parallel to the worship of Śiva and Vishnu, and to the rise of the Vedanta. Now the worship of these deities was probably not prevalent before 300 B.C., for they are almost unknown to the Pali Pitakas, and it was fully developed about the time of the Bhagavad-gîtâ which perhaps assumed its present form a little before the Christian era. Not only is the combination of devotion and metaphysics found in this work similar to the tone of many Mahayanist sutras but the manifestation of Krishna in his divine form is like the transformation scenes of the Lotus.181 The chief moral principle of the Bhagavad-gîtâ is substantially the same as that prescribed for Bodhisattvas. It teaches that action is superior to inaction, but that action should be wholly disinterested and not directed to any selfish object. This is precisely the attitude of the Bodhisattva who avoids the inaction of those who are engrossed in self-culture as much as the pursuit of wealth or pleasure. Both the Gîtâ and Mahayanist treatises lay stress on faith. He who thinks on Krishna when dying goes to Krishna182 just as he who thinks on Amitâbha goes to the Happy Land and the idea is not unknown to the Pali texts, for it finds complete expression in the story of Maṭṭhakuṇḍali.183
The idea of a benevolent deity to be worshipped with devotion and faith and not with ceremonies is strange to old Buddhism and old Brahmanism alike. It was a popular idea which became so strong that neither priests nor Bhikshus could ignore it and in its ultimate result it is hard to say whether Buddhist or Brahmanic elements are more prominent. Both Avalokita and Krishna are Devas. The former has the beauty of holiness and the strength which it gives, but also the weakness of a somewhat abstract figure: the latter is very personal and springs from the heart of India but to those who are not Hindus seems wanting in purity and simplicity. The divine character of both figures is due to Brahmanism rather than Buddhism, but the new form of worship which laid stress on a frame of mind rather than on ceremonial and the idea of Avatâras or the periodic appearance of superhuman saviours and teachers indicate the influence of Buddhism on Brahmanism.
There is a similar parallel between the newer Buddhist philosophy and the Vedantist school represented by Śankara, and Indian critics detected it. Śankara was called a Pracchanna-bauddha or crypto-buddhist by his theological opponents184 and the resemblance between the two systems in thought, if not in word, is striking. Both distinguish relative and absolute truth: for both the relative truth is practically theism, for both absolute truth is beyond description and whether it is called Brahman, Dharma-kâya or Śûnyatâ is not equivalent to God in the Christian or Mohammedan sense. Just as for the Vedantist there exist in the light of the highest knowledge neither a personal God nor an individual soul, so the Mâdhyamika Sûtra can declare that the Buddha does not really exist. The Mahayanist philosophers do not use the word Mâyâ but they state the same theory in a more subjective form by ascribing the appearance of the phenomenal world to ignorance, a nomenclature which is derived from the Buddha's phrase, "From ignorance come the Sankhâras."
Here, as elsewhere, Buddhist and Brahmanic ideas acted and reacted in such complex interrelations that it is hard to say which has borrowed from the other. As to dates, the older Upanishads which contain the foundations but not the complete edifice of Vedantism, seem a little earlier than the Buddha. Now we know that within the Vedantist school there were divergences of opinion which later received classic expression in the hands of Śankara and Râmânuja. The latter rejected the doctrines of Mâyâ and of the difference between relative and absolute truth. The germs of both schools are to be found in the Upanishads but it seems probable that the ideas of Śankara were originally worked out among Buddhists rather than among Brahmans and were rightly described by their opponents as disguised Buddhism. As early as 520 A.D. Bodhidharma preached in China a doctrine which is practically the same as the Advaita.
The earliest known work in which the theory of Mâyâ and the Advaita philosophy are clearly formulated is the metrical treatise known as the Kârikâ of Gauḍapâda. This name was borne by the teacher of Śankara's teacher, who must have lived about 700 A.D., but the high position accorded to the work, which is usually printed with the Mâṇḍûkya Upanishad and is practically regarded as185 a part of it, make an earlier date probable. Both in language and thought it bears a striking resemblance to Buddhist writings of the Mâdhyamika school and also contains many
