What specific actions of the Sadguru are mentioned in Chapter 6, and what are their transformative effects on a devotee?

Chapter 6 highlights several specific actions of the Sadguru and their powerful effects. The primary action described is the placing of His 'lotus-hand' on the devotee's head. This single act is credited with multiple transformations: it burns away the subtle body or ego, washes away the accumulated impurities of many births, and grants stability to 'nonsensical speech.' According to Chapter 6, this touch fills the heart with bliss and love. Furthermore, the Sadguru's presence awakens the 'Soham' consciousness ('I am He'), which dissolves the sense of 'me and mine' and manifests the harmony of non-duality for the devotee.
