How does Chapter 6 describe the power and impact of a Sadguru, specifically Sai Baba?

Chapter 6 eloquently details the immense power and impact of the Sadguru, using Sai Baba as the ultimate example. The text states that the Sadguru's presence is a guiding force, like a helmsman ensuring a boat reaches its destination safely, applicable to both spiritual and worldly affairs. The chapter highlights the physical and spiritual effects of the Guru's blessing hand, which, when placed on a devotee's head, can burn away the subtle body of ego into ashes. This divine touch, as described in Chapter 6, is so potent that it washes away the accumulated impurities of many lifetimes, making the devotees pure. Furthermore, the Sadguru awakens the non-dualistic realization of 'Soham' ('I am He'), dissolving the illusion of 'me and mine' and revealing innate bliss, leading to a state of supreme joy.
