What does Chapter 6 say about the role of the Sadguru in a person's life?

Chapter 6 of the Sai Satcharitra portrays the Sadguru as the essential helmsman for navigating both spiritual and worldly matters, stating that only the boat guided by a Sadguru will reach the far shore. When the name 'Sadguru' is uttered, Sai Baba is said to appear in the heart and place his blessing hand on the devotee's head. This chapter explains that the Guru's touch is powerful enough to burn away the subtle body of ego and wash away the accumulated impurities of many births. The Sadguru awakens the sense of 'I am He' (Soham), dissolving the egoic sense of 'me and mine' and manifesting the harmony of non-duality.
