Acharya Prashant addresses the fundamental inquiry into the nature of the self, or the soul, by highlighting the human discomfort with constant change and false identities. He explains that while our names, thoughts, and physical surroundings are in a state of perpetual flux, there is an inherent longing within us for something eternal and unchangeable. This search for the soul is essentially a quest for one's true identity, which remains constant amidst the shifting labels imposed by society. He uses the analogy of a bird in a cage to illustrate how we often live in a state of confinement, feeling a deep-seated restlessness because our true nature is meant for the vastness of freedom, not the limitations of worldly roles.
