According to the beginning of Chapter 6, what happens when a devotee encounters the Sadguru, and what is the effect of his blessing hand?

The start of Chapter 6 details the profound experience of encountering the Sadguru, Sai Baba. The text explains that the moment the word 'Sadguru' is spoken, Sai is remembered in the heart and feels physically present, placing his hand on the devotee's head. As Chapter 6 describes, this blessing hand, along with Udi from the Dhuni, causes the heart to overflow with self-bliss and love to pour from the eyes. The touch is so wondrous that it can burn away the subtle body of ego into ashes and wash away the accumulated impurities of many past births, making the devotees pure.
