Explain the process of ego dissolution and the realization of non-duality (Advaita) as detailed in Chapter 6.

Chapter 6 provides a profound description of the spiritual transformation facilitated by the Sadguru. It explains that the Guru's touch can burn the 'subtle body (ego) into ashes.' This is a critical step in spiritual progress. The chapter continues by stating that the Sadguru awakens the sense of 'I am He' (Soham) within the devotee, revealing their innate bliss. This awakening directly leads to the dissolution of the sense of 'me and mine,' which are constructs of the ego. As Chapter 6 culminates this idea, this process manifests the 'harmony of non-duality (Advaita),' where the devotee realizes their unity with the divine.
