Acharya Prashant explains that the ego is not the opposite of the true self, as the true self has no opposite. He describes the world of duality where opposites like black and white, day and night, or light and darkness depend on each other for their existence. In this world, one cannot identify a concept without its counterpart. However, truth exists independently and does not have an opposite. Falseness is not the opposite of truth but rather the inability or incapacity to see the truth. He uses the analogy of the sun to illustrate that even if one cannot see it, the light remains; the failure to perceive it is what is called falseness. The ego, personality, and illusions are unreal and imaginary states where one believes themselves to be something other than what they truly are. This state of unreality is what is termed falseness, but it does not negate or oppose the true self, which always is.
