How does Chapter 6 describe the power of Sai Baba's touch and blessing hand?

According to Chapter 6, the touch of Sai Baba's hand is wondrous and transformative. When his blessing hand, along with Udi from the Dhuni, is placed on a devotee's head, it's said to fill the heart with self-bliss and cause love to pour from the eyes. The text makes a powerful claim that this touch can burn the subtle body of ego into ashes, a feat that not even the fire of cosmic dissolution can accomplish. Furthermore, as described in this chapter, by placing his lotus-hand on the head, Sai washes away the accumulated impurities of many past births, purifying his loving devotees and causing their throats to choke with supreme bliss.
