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

Chapter 6 of the Sai Satcharitra vividly describes the profound effects of the Sadguru's touch. It states that when Sai Baba places His hand on a devotee's head, especially along with Udi, it fills their heart with self-bliss and brings tears of love to their eyes. This touch is described as wondrous, capable of burning away the subtle body of ego into ashes, a feat not even the fire of dissolution can achieve. According to this chapter, placing His lotus-hand on the head washes away accumulated impurities from many past births, making Sai's devotees pure and leading to the manifestation of supreme bliss.
