FOREWORD
Âcârya Sûri.
A. D. 478 In the Tattvasangraha? mention has been made of an author who is styled Acârya Sûri. This Âcârya seeins to be no other than the celebrated Haribhadra Sari of the Jainas. If we are correct in our surmise we have to identify bim with the first Haribhadra Sari who died in A. D. 4789 or Samvat 535., instead of the second Haribhadra who flourished about 1120 A. D. We do not know what works were composed by the first Haribhabra, but it is certain that he was held in high esteem as a logician and contributed materially to the development of Indian Thought. It seems quite likely that he commented on Dinnaga's Nyáyapraves'a which is being printed by the excellent Orientalist, Principal A. B. Dhruva for the Gaekwad's Oriental Series. His opinion is quoted by Kamalasila in the Svabhâvaparikşà, and the view held by him on this subject is that this diversified Universe cannot spring up without a cause, and the very reasons added in support of this theory shows that such cannot be the case. If the theory were true it must be self-existent and no reasons are required in its support.
Mâţharâcârya.
A. D. 500 Mathara the first commentator of the Sâmkhyakıarika of Isvarakļşņa is indeed not mentioned in our book either by the author or his commentator. The reason why Mâțhara comes in here is that Kamalasila has taken passages from Mathara's commentary in stating the views of the Sámkhya adherents.
Mathara has been differently placed in different centuries by eminent scholars :. 1. Tattvas. p. 66. 2. Vidyabhusana: op. cit. p. 208.
