independent text entitled "Nayacakra". In this text, it is said that by defeating Buddhism in a dispute, Logician Mallavādin reestablished the Jaina faith. Jinabhadra Gani (7th or gth cent. A.D.) is called as a great authority on the sacred literature of the Jaina-s.His text, Viseșāvasyaka Bhāsya is considered as the encyclopedia of the Jaina views'. He almost followed the definition of anekānta as accepted by the Siddhasena.Here comes to an end the period of establishment of anekānta. 1.3 Jain Logic of the Period of Pramāna Vyavasthā (8th cent. - 17th cent.
