Acharya Prashant explains that all knowledge derived from the world is inherently limited and deceptive because it asserts that the world is the only possible object of knowledge. This worldly knowledge, which includes information about the body and mind, is always based on cause, effect, and memory. He argues that such knowledge is tentative and stands on doubt, as a single piece of contrary evidence can shatter it. In contrast, true realization or 'knowing' arises instantaneously from within the self, without external cause or the need for proof. This inner knowing is characterized by total certainty and does not depend on the world's structures or scriptures.
