In Hindu philosophy, Yogaja is one of the alaukika pratyaksha – non-sensual perception of things. Alaukika pratyaksha is perception through extraordinary (in contrast to the ordinary) channels, i.e. not through the senses. This concept seems to be the contribution of the Naiyayikas (logicians), beginning with Gangesha Upadhyaya. Three kinds of extraordinary perception have been identified – samanya lakshana pratyasatti, jnana lakshana pratyasatti and yogaja.
Yogaja is a super-sensuous intuition of things and events in the past, present and future. This power of omniscience is possessed by the accomplished yogins. Others will have to exercise their powers of concentration to acquire this power. These are respectively called the yukta yogins and the yunjana yogins.
