What are the specific effects of Sai Baba's touch on a devotee, according to the beginning of Chapter 6?

According to Chapter 6, the touch of Sadguru Sai Baba's hand has profound and transformative effects on a devotee. When His blessing hand, along with Udi from the Dhuni, falls upon someone's head, their heart overflows with self-bliss and love pours from their eyes. The text emphasizes that this touch is wondrous and possesses a unique power; it can burn away the subtle body, or ego, which even the fire of dissolution cannot destroy. As the chapter further details, by placing His lotus-hand on a devotee's head, the accumulated impurities from many past births are washed away, leading to a state of purity.
