A corrupt form of Buddhism still exists in Nepal.[290] This country when first heard of was in the hands of the Nevars who have preserved some traditions of a migration from the north and are akin to the Tibetans in race and language, though like many non-Aryan tribes they have endeavoured to invent for themselves a Hindu pedigree. Buddhism was introduced under Asoka. As Indian influence was strong and communication with Tirhut and Bengal easy, it is probable that Buddhism in Nepal reflected the phases which it underwent in Bengal. A Nepalese inscription of the seventh century gives a list of shrines of which seven are Śivaite, six Buddhist and four Vishnuite.[291] After that date it was more successful in maintaining itself, for it did not suffer from Mohammedan attacks and was less exposed to the assimilative influence of Brahmanism. That influence however, though operating in a foreign country and on people not bred among Brahmanic traditions, was nevertheless strong. In 1324 the king of Tirhut, being expelled thence by Mohammedans, seized the throne of Nepal and brought with him many learned Brahmans. His dynasty was not permanent but later in the fourteenth century a subsequent ruler, Jayasthiti, organized society and religion in consultation with the Brahman immigrants. The followers of the two religions were arranged in parallel divisions, a group of Buddhists classified according to occupation corresponding to each Hindu caste, and appropriate rules and ceremonies were prescribed for the different sections. The code then established is still in force in essentials and Nepal, being intellectually the pupil of India, has continued to receive such new ideas as appeared in the plains of Bengal. When these ascended to the mountain valleys they were adopted, with free modification of old and new material alike, by both Buddhists and Hindus, but as both sects were geographically isolated, each tended to resemble the other more than either resembled normal Buddhism or Hinduism. Naturally the new ideas were mainly Brahmanic and Buddhism had no chance of being fortified by an importation of even moderately orthodox doctrine. In the fourteenth century arose the community of wandering ascetics called Nâthas who were reverenced by Hindus and Buddhists alike. They rejected the observances of both creeds but often combined their doctrines and, though disavowed by the Brahmans, exercised a considerable influence among the lower castes. Some of the peculiar deities of Nepal, such as Matsyendranâth, have attributes traceable to these wanderers. In 1769 Nepal was conquered by the Gurkhas. This tribe seems related to the Tibetan stock, as are the Nevars, but it had long been Hinduized and claimed a Rajput ancestry. Thus Gurkha rule has favoured and accelerated the hinduizing of Nepalese Buddhism.
