How does Chapter 6 of Sai Satcharitra describe the power of a Sadguru's blessing and touch?

Chapter 6 of the Shri Sai Satcharitra vividly portrays the immense power of a Sadguru's blessing. It states that when Sai Baba, the Sadguru, places His hand on a devotee's head along with Udi from the Dhuni, the devotee's heart fills with self-bliss. This touch is described as wondrous and capable of burning away the subtle body of ego, a feat that even the fire of dissolution cannot accomplish. Furthermore, the chapter explains that the simple act of placing His lotus-hand on a devotee's head can wash away the accumulated impurities of many births, rendering the devotee pure and bringing tears of joy to their eyes.
