Perception is direct knowledge and definite truth
For Hindu Nayaya, perception is the definite and true knowledge. Knowledge because of stimulation of sense organs perceiving objects directly is definitely a cognition. Nyaya Sutra defined perception as a definite cognition which is produced by sense object contact and it is therefore true or unerring. For example, seeing a cow with four legs, two horns, tail and same shape give us knowledge that cow is coming from opposite side. Similarly, a table in front of me and a fan on the roof hanging over me is the plane definition of perception. Now Nayayaikas went deep in describing the concept of perception, they said that there are classified into two types in which first is ordinary (laukika) and another is extraordinary (alaukika). The ordinary perception is a simple way in which usual way sense comes into contact with the objects presented but in extraordinary perception in which an object as such is not ordinarily present to senses but is conveyed to sense through perception.
