Can you explain the philosophical concept of 'I and mine' as a delusion, and how one can transcend this state to achieve self-realization according to Chapter 17?

Chapter 17 delves into the advanced concept that the sense of "I and mine" is a delusion, or a "confusion of bodily ego," that stems from the illusion of Maya. This perspective is compared to a mirage, something that appears real but has no substance. To transcend this, the chapter advises one to think clearly and not get entangled in the world of "me and you." It uses the metaphor of a parrot tied to a tube, urging the soul to "release the feet that are held tight... and fly high in the sky." As long as the "me and you" perspective dominates, one cannot see their own welfare. Chapter 17 teaches that by discarding this limited view and focusing on the Self, one can acquire special knowledge (Vijnana) and realize the knowledge of Brahman that is already near.
