What does Chapter 6 of the Sai Satcharitra say about the power of a Sadguru's blessing?

According to Chapter 6 of the Sai Satcharitra, the power of a Sadguru's blessing is immense and transformative. The chapter describes that when the Sadguru, Sai Baba, places His blessing hand along with Udi on a devotee's head, their heart overflows with self-bliss. This touch is described as wondrous, capable of burning away the subtle body, or ego, into ashes—a feat that even the fire of dissolution cannot achieve. The text further explains that by placing His lotus-hand on the head, the accumulated impurities of many past births are washed away, rendering Sai's loving devotees pure and leading them towards spiritual realization.
