How does Chapter 6 describe the power of a Sadguru's touch and blessing?

Chapter 6 of the Shri Sai Satcharitra beautifully illustrates the profound power of a Sadguru's blessing. It describes how the Sadguru, like a helmsman, safely guides a devotee's boat to the far shore. When Sai Baba places his blessing hand, along with Udi, upon a devotee's head, their heart overflows with self-bliss. The text emphasizes the wondrous nature of this touch, stating it can burn away the subtle body, or ego, into ashes—something even the fire of dissolution cannot do. Furthermore, as noted in Chapter 6, placing his lotus-hand on the head washes away the accumulated impurities of many past births, purifying his loving devotees.
