The text talks about Sai Baba placing his hand on people's heads. What happens when he does this, according to Chapter 6?

Chapter 6 of the Sai Satcharitra beautifully describes the profound effects of the Sadguru's touch. When Sai Baba places his blessing hand, sometimes accompanied by Udi from the Dhuni, on a devotee's head, their heart overflows with self-bliss and love pours from their eyes. This wondrous touch has the power to burn away the subtle body, or ego, into ashes—something the text says even the fire of dissolution cannot destroy. As this chapter explains, by placing his lotus-hand on the head, Sai washes away the accumulated impurities of many past births, making his loving devotees pure.
