Something has already been said of the two other schools, both of which denied the reality of the external world. The differences between them were concerned with metaphysics rather than theology and led to no popular controversies.
Up to this point the history of Indian Buddhism has proved singularly nebulous. The most important dates are a matter of argument, the chief personages half mythical. But when the records of the Chinese pilgrims commence we are in touch with something more solid. They record dates and facts, though we must regret that they only repeat what they heard and make no attempt to criticize Indian traditions or even to weave them into a connected chronicle.
Fa-Hsien, the first of these interesting men, left China in 399 and resided in India from 405 to 411, spending three years at Pataliputra and two at Tamralipti. He visited the Panjab, Hindustan and Bengal and his narrative leaves the impression that all these were in the main Buddhist countries: of the Deccan which he did not visit he heard that its inhabitants were barbarous and not Buddhists, though it contained some Buddhist shrines. Of the Middle Kingdom (which according to his reckoning begins with Muttra) he says that the people are free and happy and neither kill any living creature nor drink intoxicating liquor.[236] He does not hint at persecution though he once or twice mentions that the Brahmans were jealous of the Buddhists. Neither does he indicate that any strong animosity prevailed between Maha and Hinayanists. But the two parties were distinct and he notes which prevailed in each locality. He left China by land and found the Hinayana prevalent at Shen-shen and Wu-i (apparently localities not far from Lob-Nor) but the Mahayana at Khotan. Nearer India, in countries apparently corresponding to parts of Kashmir and Gilgit, the monks were numerous and all Hinayanist. The same was the case in Udyana, and in Gandhara the Hinayanists were still in the majority. In the Panjab both schools were prevalent but the Hinayana evidently strong. In the district of Muttra the Law was still more flourishing, monasteries and topes were numerous and ample alms were given to the monks. He states that the professors of the Abhidharma and Vinaya made offerings to those works, and the Mahayanists to the book Prajñâ-pâramitâ, as well as to Mañjusrî and Kwan-shih-yin. He found the country in which are the sacred sites of Srâvasti, Kapilavastu and Kusinârâ sparsely inhabited and desolate, but this seems to have been due to general causes, not specially to the decay of religion. He mentions that ninety-six[237] varieties of erroneous views are found among the Buddhists, which points to the existence of numerous but not acutely hostile sects and says that there still existed, apparently in Kosala, followers of Devadatta who recognized three previous Buddhas but not Sâkyamuni. He visited the birth-places of these three Buddhas which contained topes erected in their honour.
