How does Chapter 6 of Sai Satcharitra describe the power and grace of a Sadguru, specifically referring to Sai Baba?

Chapter 6 of the Sai Satcharitra beautifully illustrates the profound power and grace of a Sadguru like Sai Baba. It states that the Sadguru's blessing hand, when placed on a devotee's head, can burn away the ego, which is described as a subtle body that even the fire of dissolution cannot destroy. This act purifies the devotee, washing away the accumulated impurities of many births. As mentioned in the chapter, with the Sadguru as the helmsman, any boat, whether for spiritual or worldly matters, will safely reach its destination, highlighting the Guru's indispensable guidance.
