How does Chapter 6 describe the importance and power of a Sadguru, specifically in relation to Sai Baba?

Chapter 6 of the Sai Satcharitra opens by glorifying the Sadguru, likening him to a helmsman who can guide the boat of one's life to the "far shore," whether in worldly or spiritual affairs. The chapter states that the very word 'Sadguru' brings Sai Baba immediately to mind, who then places His blessing hand on the devotee's head. This sacred touch, often accompanied by Udi from the Dhuni, is described as filling the heart with self-bliss and love. As this chapter explains, the Guru's power is wondrous, capable of burning away the subtle body of ego into ashes, a feat that even the fire of cosmic dissolution cannot accomplish.
