How does Chapter 6 describe the effect of Sai Baba's blessing hand on his devotees?

Chapter 6 of the Sai Satcharitra details the profound and transformative power of the Sadguru's touch. It states that when Sai Baba places his blessing hand, especially when accompanied by Udi from the Dhuni, on a devotee's head, their heart overflows with self-bliss and love. The text describes this touch as wondrous, capable of burning away the subtle body of ego into ashes—a feat not even the fire of dissolution can achieve. According to Chapter 6, this simple act of placing his lotus-hand on the head washes away the accumulated impurities of many past births, purifying Sai's devotees and allowing them to experience supreme bliss.
