The Satcharitra mentions Sai Baba placing his hand on people's heads. What is the significance of this act according to Chapter 6?

According to Chapter 6 of the Sai Satcharitra, the touch of the Sadguru's hand is profoundly transformative. When Sai Baba places his blessing hand on a devotee's head, especially when accompanied by Udi from the Dhuni, it fills the heart with self-bliss and evokes tears of love. The text describes this touch as wondrous, capable of burning away the subtle body or ego into ashes, a feat not even possible in the fire of dissolution. Furthermore, the scripture states that by placing his lotus-hand on the head, Sai Baba washes away the accumulated impurities of many past births, making his devotees pure.
