How does Chapter 6 describe the power and effect of a Sadguru's touch, particularly Sai Baba's?

According to Chapter 6 of the Sai Satcharitra, the touch of a Sadguru like Sai Baba is wondrous and transformative. When His blessing hand, accompanied by Udi, is placed on a devotee's head, the heart overflows with self-bliss and love. This sacred touch has the power to burn away the subtle body of ego, which even the fire of dissolution cannot destroy. Furthermore, the text explains that by placing His lotus-hand on a devotee's head, the accumulated impurities from many past births are washed away, making them pure. This interaction can be so powerful that it chokes the throat with supreme bliss and brings tears of joy to the eyes.
