This chapter examines how the Jains tried to show the possibility of an all-knowing person, and discusses why the Jains are so eager to establish the omniscience of the savior on the basis of some Prakrit and Sanskrit treatises such as the Rajapraseniya, and Aptamimamsa. Before discussing the attempts to prove the existence of the omniscience in Jainism, it provides a brief view at Jain epistemology. The Jains admit the two kinds of valid method of knowledge (pramana): pratyaksa and paroksa. In the first syllogism Samantabhadra proclaims that only the Jain tirthamkara is omniscient, he who has destroyed all hindrances and recognizes all the things in this universe. Hemacandra, philosophical giant of the Jain tradition, combines the traditional idea of sarvajna with that of Samantabhadra and Akalanka when he discusses the concept of omniscience in his Pramanamimamsa. According to Jainism people cannot realize themselves whether they have the possibility of moksa or not.
