Satindra Chandra Nyāyāchārya presents an outline of Jaina philosophy in this book. The author argues that Syādvāda and Nayavāda are the two main fundamental theses of Jainism. The book contains a detailed presentation of the Jaina theory of pramāṇa. The author explains why the Jainas accept pratyabhijñā as an indirect pramāṇa. There is also a discussion on the Jaina view that upamāṇa pramāṇa could be included in pratyabhijñā. The author ends his discourse with a discussion on Nayavāda.
