What does Chapter 6 say about the power of a Sadguru's touch, specifically Sai Baba's?

Chapter 6 of the Shri Sai Satcharitra explains the profound impact of the Sadguru's touch. When Sai Baba places his blessing hand, along with Udi from the Dhuni, on a devotee's head, the heart overflows with self-bliss and love pours from the eyes. The text poetically describes this touch as wondrous, capable of burning away the subtle body of ego into ashes, something even the fire of dissolution cannot do. As mentioned in this chapter, placing his lotus-hand on the head is said to wash away the accumulated impurities of many lifetimes, making Sai's loving devotees pure.
