Acharya Prashant explains that the purification of the inner self involves the removal of the ego. He clarifies that the ego is the pollutant that defiles whatever it attaches itself to. Contrary to the common belief that the world or external thoughts corrupt the individual, he asserts that it is the ego's touch that makes things impure. He uses the analogy of a forest, which remains pure despite birth, death, and decay because it is untouched by human ego, whereas even a clean house feels cluttered and impure due to the ego's presence. A pure inner self is one that is solitary and free from the ego's expectations of fulfillment and completion. The ego, driven by a sense of incompleteness, constantly seeks to attach itself to objects, bodies, and ideas, hoping to find wholeness. Acharya Prashant notes that while the ego naturally attaches to one's own body, it can easily shift its claim to others' bodies or external objects, leading to corruption and bondage. He distinguishes between the ego's attachment to small, limited things and its movement toward the vast or the infinite. When the ego connects with the immense, it leads to surrender and the breaking of its own boundaries. He emphasizes that the purpose of this understanding is not to collect intellectual knowledge but to bring about a fundamental transformation in one's life and conduct.
