Various other works are ascribed to Aśvaghosha and for the history of Buddhism it is of great interest to decide whether he was really the author of _The Awakening of Faith_. This skilful exposition of a difficult theme is worthy of the writer of the Buddhacarita but other reasons make his authorship doubtful, for the theology of the work may be described as the full-blown flower of Mahayanism untainted by Tantrism. It includes the doctrines of Bhûta-tathatâ, Âlaya-vijñâna, Tathâgatagarbha and the three bodies of Buddha. It would be dangerous to say that these ideas did not exist in the time of Kanishka, but what is known of the development of doctrine leads us to expect their full expression not then but a century or two later and other circumstances raise suspicions as to Aśvaghosha's authorship. His undoubted works were translated into Chinese about 400 A.D. but _The Awakening of Faith_ a century and a half later.[207] Yet if this concise and authoritative compendium had existed in 400, it is strange that the earlier translators neglected it. It is also stated that an old Chinese catalogue of the Tripitaka does not name Aśvaghosha as the author.[208] The undoubted works of Aśvaghosha treat the Buddha with ornate but grave rhetoric as the hero of an epic. His progress is attended by miracles such as Indian taste demands, but they hardly exceed the marvels recounted in the Pali scriptures and there is no sign that the hero is identified, as in the Ramayana of Tulsi Das or the Gospel according to St. John, with the divine spirit. The poet clearly feels personal devotion to a Saviour. He dwells on the duty of teaching others and not selfishly seeking one's own salvation, but he does not formulate dogmas. The name most definitely connected with the early promulgation of Mahayanism is Nâgârjuna.[209] A preponderance of Chinese tradition makes him the second patriarch after Aśvaghosha[210] and this agrees with the Kashmir chronicle which implies that he lived soon after Kanishka.[211] He probably flourished in the latter half of the second century. But his biographies extant in Chinese and Tibetan are almost wholly mythical, even crediting him with a life of several centuries, and the most that can be hoped is to extract a few grains of history from them. He is said to have been by birth a Brahman of Vidarbha (Berar) and to have had as teacher a Sudra named Saraha or Râhulabhadra. When the legend states that he visited the Nâgas in the depths of the sea and obtained books from them, it seems to admit that he preached new doctrines. It is noticeable that he is represented not only as a philosopher but as a great magician, builder, physician, and maker of images.
