How does Chapter 6 describe the power and glory of a Sadguru like Sai Baba?

Chapter 6 of the Sai Satcharitra beautifully illustrates the immense power and glory of the Sadguru. It begins by stating that any endeavor, whether spiritual or worldly, will succeed if the Sadguru is the guide, likening him to a helmsman steering a boat to the far shore. As detailed in the chapter, the mere utterance of the word 'Sadguru' brings Sai Baba to mind, who then places his blessing hand on the devotee's head. This touch is described as wondrous, capable of burning away the ego (subtle body) into ashes and washing away the accumulated impurities of many lifetimes, making the devotees pure.
