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

Chapter 6 of the Sai Satcharitra begins by extolling the virtues of a Sadguru, describing their role as a helmsman who guides a devotee's boat to the far shore. It emphasizes the wondrous power of the Guru's touch, stating that it can burn away the subtle body of ego into ashes. The chapter explains that when the Sadguru's blessing hand, especially when accompanied by Udi from the Dhuni, is placed on a devotee's head, their heart overflows with bliss. This sacred act is said to wash away the accumulated impurities of many lifetimes, leaving Sai's devotees pure and filled with love.
