According to Chapter 6, what is the transformative effect of Sai Baba's touch on a devotee's ego and spiritual purity?

Chapter 6 of the Sai Satcharitra details the profound transformative power of the 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 even the fire of dissolution cannot do. By placing His lotus-hand on a devotee's head, Sai Baba washes away the accumulated impurities of many past lives, rendering the devotee pure. This sacred touch, often accompanied by Udi from the Dhuni, fills the heart with self-bliss and purifies the individual from deep-seated karmic baggage, as described in the chapter.
