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

Chapter 6 of the Shri Sai Satcharitra details the profound and transformative power of the Sadguru's touch. It explains that when Sai Baba places His hand on a devotee's head, especially when accompanied by Udi from the Dhuni, the person's heart overflows with self-bliss and love. This touch is described as wondrously potent, capable of burning away the subtle body of ego into ashes—something even the fire of dissolution cannot achieve. Furthermore, the chapter states that by placing His lotus-hand on the head, the accumulated impurities from many past births are washed away, purifying Sai's loving devotees. This highlights the immense grace and purifying capacity inherent in the Sadguru's physical blessing as described in Chapter 6.
