What does Chapter 6 say about the power of the Sadguru's hand and touch?

Chapter 6 of the Sai Satcharitra extensively details the wondrous power of the Sadguru's touch. It explains that when Sai Baba places His blessing hand on a devotee's head, especially along with Udi from the Dhuni, the person's heart overflows with self-bliss and love. This touch is described as so potent that it can burn away the subtle body of ego into ashes, a feat that even the fire of dissolution cannot accomplish. Furthermore, the chapter states that by placing His lotus-hand on the head, the accumulated impurities of many past births are washed away, leaving Sai's loving devotees pure.
