Acharya Prashant explains that knowledge, as described by Shri Krishna in the Bhagavad Gita, is not the sensual, memory-based information we typically acquire from the world. Instead, true knowledge is a purifier that helps one see the limitations of worldly knowledge. While the world provides external, sensual inputs that lead to bondage and ego-centered consciousness, real knowledge arises from within and is spontaneous, causeless, and independent of the senses. This inner knowing is the nature of the self and acts as a fire that burns away everything unoriginal and fake, leading to a state of yoga.
