How does Chapter 6 articulate the concept of destroying the ego or 'subtle body' and achieving a state of non-duality (Advaita)?

Chapter 6 delves into advanced spiritual concepts, explaining that the touch of the Guru's hand is wondrously powerful. It states that the Sadguru can burn away the 'subtle body,' which is equated with the ego, into ashes—a feat that even the fire of cosmic dissolution cannot achieve. This destruction of the ego is a critical step towards higher realization. The chapter connects this to the manifestation of non-duality, or Advaita. It clarifies that the Sadguru awakens the sense of 'I am He' (Soham) and dissolves the sense of 'me and mine,' which allows the devotee to experience innate bliss and the harmony of non-duality directly.
