________________ Nos. 3 & 4] VIDYANANDA AND PATRAKESARI longing to a rival school of thought, which is quite common in the philosophical literature of India. By " Abrika" other Buddhist writers may here refer to the Digambara school. The identification of the Karikas found in the Visalamalavati tika with those found in the works of Santa raksita and Kamalasila suggests that Patrasvamia or Patrakesari was a teacher of the Digambara school of the Jains who attained glory by the refutation of the Trilaksana doctrine of Hetu, known to have been well established by Dinnaga. This pushes the date of Patrakesari further back and suggests that Patrakesari must have lived sometime after Dinnaga and before Dharmakirti. It is far from truth to say that Patrakesari is identical with Vidyananda, the author of Slokavartika, who actually quotes from the works of Dharmakirti and is assigned to 9th Century A.D.
