According to Chapter 6 of the Sai Satcharitra, what is the significance and power of a Sadguru's touch?

Chapter 6 of the Sai Satcharitra elaborates on the profound power of a Sadguru's touch. It states that the touch of the Guru's hand is wondrous, capable of burning away the subtle body, or ego, into ashes—something that even the fire of dissolution cannot do. The chapter further explains that when the Sadguru, Sai, places His lotus-hand on a devotee's head, the accumulated impurities from many previous births are washed away, rendering the devotee pure. This blessed touch, especially when accompanied by Udi, fills the heart with self-bliss and causes love to pour from the eyes.
