How does the text differentiate between the perceived self, which is bound to the ego, and the true Self, which is the ultimate reality?

Chapter 19 draws a sharp distinction between the perceived self and the true Self. The perceived self is defined by the ego, specifically the false notion of 'I am the body.' This ego creates the sense of being a 'doer' and 'enjoyer,' which makes the experience of pleasure and pain unavoidable. This is described as a false bondage, like mistaking a rope for a snake. In contrast, the true Self, or Soul, is described as changeless, formless, and imperishable. It is pure consciousness, distinct from the body, senses, and mind. The ultimate goal, or Pure Brahman, is the realization of this true Self, where the senses and mind finally find rest.
