How does Chapter 6 describe the transformative power of a Sadguru's touch on a devotee?

Chapter 6 of the Shri Sai Satcharitra explains the profound and transformative power of a Sadguru's touch. It states that when Sai Baba places his blessing hand on a devotee's head, it can burn away the subtle body of ego, a feat that even the fire of dissolution cannot accomplish. This divine touch is also described as washing away the accumulated impurities of many past births, purifying the devotee completely. According to this chapter, the experience fills the devotee's heart with self-bliss and causes tears of love and joy to flow, demonstrating the deep spiritual purification and emotional upliftment granted by the Guru's grace.
