How does Chapter 6 describe the power of a Sadguru's touch and blessing, specifically referring to Sai Baba?

Chapter 6 of the Sai Satcharitra explains that the Sadguru's power is immense and transformative. It states that when Sai Baba places His blessing hand on a devotee's head, the heart overflows with self-bliss. This touch is described as wondrous, capable of burning away the subtle body of ego into ashes, something that even the fire of dissolution cannot achieve. The chapter further elaborates that by placing His lotus-hand on the head, the accumulated impurities from many past births are washed away, rendering Sai's devotees pure. This divine contact is a central theme, highlighting the Guru's ability to purify and elevate the disciple through a simple, loving gesture.
