Acharya Prashant explains that the world, including all beings, Vedas, and gods, is essentially a projection of the mind and not separate from the self. He asserts that suffering arises solely because individuals perceive the world as a reality in itself rather than a mental image. When one views the world as an independent reality, they define themselves as small and limited, leading to a life driven by fear and greed. This smallness is contrary to our true nature, which is infinite and limitless, often referred to as 'Brahman'.
