Acharya Prashant explains that living without belief is essential, as all beliefs, including the belief in God, originate from the same center of self-belief or the ego. He argues that when a person believes in an external object or experience without investigation, they are fundamentally believing in their own perception and self-importance. This misplaced confidence leads the ego to conclude that because it is real, everything it perceives must also be real. This logic eventually necessitates the concept of a God as a creator of this perceived reality, making God a logical extension of the believer's own ego and insecurity.
