Can you explain the philosophy behind transcending the ego, or 'I and mine', as discussed in Chapter 17?

Chapter 17 delves into the advanced philosophical concept of transcending the ego. It explains that the sense of self, expressed as "I and mine," is a delusion born from Maya, or illusion, which causes a "confusion of bodily ego." This confusion makes a person forget their true, divine nature. The text compares this ego-identity to a mirage and strongly advises one to become free of 'mine-ness'. It argues that as long as the duality of "me and you" persists in one's consciousness, one cannot be the "seer of your own welfare." The ultimate goal is to discard this limited identity, look at the true Self, and, like a parrot freeing itself from a tube, fly high into the sky of spiritual liberation, transcending both bondage and freedom to remain in a pure, self-controlled state.
