Preface
was later on done by Jinabhadra Gani Kşamāśramaņa (circa 6th century A. D. ). This state of affairs which must have existed even prior to the life-time of these Jaina pontiffs, seems to have resulted in the formulation of a rule that the principles of Jainism deserve to be studied, examined and propounded from the stand-point of hetu-vada and agama-vada as well, so far as they are confined to their own spheres. To be explicit, a principle which is within the domain of agama-vada should not be subjected to that of hetu-vada and vice versa.
Jinabhadra Gaņi Kşamāśramaņa and Sanghadāsa have treated the Jaina philosophical doctrines in their bhasas on agamas, the former in Visesavassayabhasa and the latter in his bhasa on Kappa.
Amongst the non-canonical works on philosophy Tattvarthadhigamasutra of Umāsväti and its commentaries by Svetāmbara and Digam bara writers of celebrity may be specially noted. The doctrine of nayas is here treated. It is dealt with by Siddhasena Divākara in his Sammaipayarana (Sammati-prakarana ) and Nyayavatāra and by Mallavădin in his Dvadašara-naya cakra, a commentary by himself on his single verse of deep meaning. This commentary is splendidly elucidated by Simhasüra Gani in his commentary known as Nayacakravala or Nyāyāgamanusarini ţika. The work of Mallavădin is preceded by Saptašatara-nayacakra lost long long ago. This prepared a back-ground for the treatment of syadvada, and Haribhadra took advantage of this situation, and gave us a splendid and comprehensive work viz. Anekantajayapataka. Herein he has refuted the views of different schools of Buddhism. He has quoted from 'some work of Puruşacandra, a logician. Vādin Deva Sūri ard Hemacandra ( Kalikalasarvajña ) have given us treatises on logic. Anekantavyavastha of Yašovijaya Gaņi is perhaps the last Svetāmbra work on logic worthy of mention.
As stated in Prabhavakacarita ( X,37-38 ) Jinayaśas ( ? Ajitayaśas) composed Pramana-grantha (a work on logic) and nyasa on Višrantavid,adhara (grammar). None of these has been so far traced.
1 In v. 2180-2278 there is a detailed exposition of nayas.
