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

According to Chapter 6 of the Sai Satcharitra, the touch of the Sadguru's hand is wondrous and transformative. When Sai Baba places his blessing hand, along with Udi from the Dhuni, on a devotee's head, their heart overflows with self-bliss. This sacred touch is said to burn away the subtle body of ego into ashes, something even the fire of dissolution cannot do. The text further explains that by placing His lotus-hand on a devotee's head, the accumulated impurities of many past births are washed away, purifying them completely.
