What does Chapter 6 of the Sai Satcharitra teach about the role and glory of a Sadguru?

Chapter 6 of the Sai Satcharitra beautifully illustrates the supreme importance and glory of the Sadguru. It begins by stating that whether for spiritual or worldly matters, a boat can only reach the far shore if the Sadguru is the helmsman. This chapter explains that the Sadguru's blessing hand, when placed on a devotee's head, can burn away the subtle body of ego, an act more powerful than the fire of dissolution. The text further elaborates that by placing His lotus-hand on the head, the Sadguru washes away the accumulated impurities of many births, making the devotees pure. By surrendering to a capable Sadguru like Sai, the four main goals of life—Dharma, Artha, Kama, and Moksha—can be attained naturally.
