What are the core teachings about the Sadguru's power presented at the beginning of Chapter 6 of the Sai Satcharitra?

Chapter 6 begins by glorifying the Sadguru, identifying this spiritual guide with Sai Baba. The core teaching is that the Sadguru is the essential 'helmsman' who can steer both the spiritual and worldly 'boat' to its destination. The chapter emphasizes the miraculous power of the Guru's touch, explaining that when His blessing hand is placed on a devotee's head, it can burn away the subtle body of ego, which is something not even the fire of dissolution can do. This touch washes away the impurities of many births, granting self-bliss and causing love to pour from the eyes of the devotee.
