How does Chapter 6 describe the spiritual transformations that occur when a devotee receives the Sadguru's blessing hand on their head?

Chapter 6 explains that the Sadguru's blessing initiates profound spiritual changes. When Sai Baba places His lotus-hand on a devotee's head, the accumulated impurities of many lifetimes are washed away, rendering them pure. This experience brings supreme bliss, causing the throat to choke up and tears of joy to flow. Ultimately, the Sadguru's grace awakens the sense of 'I am He' (Soham), dissolving the illusion of 'me and mine' and manifesting the harmony of non-duality, or Advaita, within the devotee.
