In the Vedantic view, the vyapti is also considered as essential for any inference. The vyapti states an invariable and unconditional relationship between two terms.

The vedantins follow the method of repeated observations of concomitant relation and non- observation of contrary instances, (vyabhicaradarsana sati sahalara darsanam) in order to establish the relation of vyapti. That is why they don’, claim the possibility of necessary relationship between the vyapya and vyapaka.

The relation vyapti, according to vedantins, is only contingent or probable in nature. Through the varieties of observations the vyapti is ascertained with more certainty but not with absolute certainty.
