Ample as are the materials for the study of Buddhism in Central Asia those hitherto published throw little light on the time and manner of its introduction. At present much is hypothetical for we have few historical data—such as the career of Kumârajîva and the inscription on the Temple of Maitreya at Turfan—but a great mass of literary and artistic evidence from which various deductions can be drawn.

It is clear that there was constant intercourse with India and the Oxus region. The use of Prakrit and of various Iranian idioms points to actual colonization from these two quarters and it is probable that there were two streams of Buddhism, for the Chinese pilgrims agree that Shan-shan (near Lob-nor), Turfan, Kucha and Kashgar were Hînayânist, whereas Yarkand and Khotan were Mahâyânist. Further, much of the architecture, sculpture and painting is simply Gandharan and the older specimens can hardly be separated from the Gandharan art of India by any considerable interval. This art was in part coeval with Kanishka, and if his reign began in 78 A.D. or later the first specimens of it cannot be much anterior to the Christian era. The earliest Chinese notices of the existence of Buddhism in Kashgar and Kucha date from 400 (Fa-Hsien) and the third century (Annals of the Tsin, 265-317) respectively, but they speak of it as the national religion and munificently endowed, so that it may well have been established for some centuries. In Turfan the first definite record is the dedication of a temple to Maitreya in 469 but probably the history of religion there was much the same as in Kucha.

It is only in Khotan that tradition, if not history, gives a more detailed narrative. This is found in the works of the Chinese pilgrims Hsüan Chuang and Sung Yün and also in four Tibetan works which are apparently translated from the language of Khotan[518]. As the story is substantially the same in all, it merits consideration and may be accepted as the account current in the literary circles of Khotan about 500 A.D. It relates that the Indians who were part-founders of that city in the reign of Asoka were not Buddhists[519] and the Tibetan version places the conversion with great apparent accuracy 170 years after the foundation of the kingdom and 404 after the death of the Buddha. At that time a monk named Vairocana, who was an incarnation of Manjuśri, came to Khotan, according to Hsüan Chuang from Kashmir[520]. He is said to have introduced a new language as well as Mahâyânism, and the king, Vijayasambhava, built for him the great monastery of Tsarma outside the capital, which was miraculously supplied with relics. We cannot be sure that the Tibetan dates were intended to have the meaning they would bear for our chronology, that is about 80 B.C., but if they had, there is nothing improbable in the story, for other traditions assert that Buddhism was preached in Kashmir in the time of Asoka. On the other hand, there was a dynastic change in Khotan about 60 A.D. and the monarch who then came to the throne may have been Vijayasambhava.

According to the Tibetan account no more monasteries were built for seven reigns. The eighth king built two, one on the celebrated Gośirsha or Gośringa mountain. In the eleventh reign after Vijayasambhava, more chaityas and viharas were built in connection with the introduction of the silkworm industry. Subsequently, but without any clear indication of date, the introduction of the Mahâsanghika and Sarvâstivâdin schools is mentioned.

The Tibetan annals also mention several persecutions of Buddhism in Khotan as a result of which the monks fled to Tibet and Bruzha. Their chronology is confused but seems to make these troubles coincide with a persecution in Tibet, presumably that of Lang-dar-ma. If so, the persecution in Khotan must have been due to the early attacks of Mohammedans which preceded the final conquest in about 1000 A.D.[521]

Neither the statements of the Chinese annalists about Central Asia nor its own traditions prove that Buddhism flourished there before the Christian era. But they do not disprove it and even if the dream of the Emperor Ming-Ti and the consequent embassy are dismissed as legends, it is admitted that Buddhism penetrated to China by land not later than the early decades of that era. It must therefore have been known in Central Asia previously and perhaps Khotan was the place where it first flourished.

It is fairly certain that about 160 B.C. the Yüeh-chih moved westwards and settled in the lands of the Oxus after ejecting the Sakas, but like many warlike nomads they may have oscillated between the east and west, recoiling if they struck against a powerful adversary in either quarter. Le Coq has put forward an interesting theory of their origin. It is that they were one of the tribes known as Scythians in Europe and at an unknown period moved eastwards from southern Russia, perhaps leaving traces of their presence in the monuments still existing in the district of Minussinsk. He also identifies them with the red-haired, blue-eyed people of the Chotscho frescoes and the speakers of the Tokharian language. But these interesting hypotheses cannot be regarded as proved. It is, however, certain that the Yüeh-chih invaded India[522], founded the Kushan Empire and were intimately connected (especially in the person of their great king Kanishka) with Gandharan art and the form of Buddhism which finds expression in it. Now the Chinese pilgrim Fa-Hsien (c. 400) found the Hînayâna prevalent in Shan-shan, Kucha, Kashgar, Osh, Udyana and Gandhara. Hsüan Chuang also notes its presence in Balkh, Bamian, and Persia. Both notice that the Mahâyâna was predominant in Khotan though not to the exclusion of the other school. It would appear that in modern language the North-West Frontier province of India, Afghanistan, Badakshan (with small adjoining states), the Pamir regions and the Tarim basin all accepted Gandharan Buddhism and at one time formed part of the Kushan Empire.

It is probably to this Gandharan Buddhism that the Chinese pilgrims refer when they speak of the Sarvâstivâdin school of the Hînayâna as prevalent. It is known that this school was closely connected with the Council of Kanishka. Its metaphysics were decidedly not Mahâyânist but there is no reason why it should have objected to the veneration of such Bodhisattvas as are portrayed in the Gandhara sculptures. An interesting passage in the life of Hsüan Chuang relates that he had a dispute in Kucha with a Mahâyânist doctor who maintained that the books called Tsa-hsin, Chü-shê, and P'i-sha were sufficient for salvation, and denounced the Yogaśâstra as heretical, to the great indignation of the pilgrim[523] whose practical definition of Mahâyânism seems to have been the acceptance of this work, reputed to have been revealed by Maitreya to Asanga. Such a definition and division might leave in the Hînayâna much that we should not expect to find there.

The Mahâyânist Buddhism of Khotan was a separate stream and Hsüan Chuang says that it came from Kashmir. Though Kashmir is not known as a centre of Mahâyânism, yet it would be a natural route for men and ideas passing from any part of India to Khotan.
