How does Chapter 10 describe the role of a Sadguru like Sai Baba in a devotee's life?

Chapter 10 portrays the Sadguru, Sai Baba, as the one eternal God who can alter a devotee's fate, a power described as being able to "strike a nail over the lines of destiny." The text emphasizes that placing faith in the Guru's feet is paramount. According to this chapter, the Guru acts as a boatman, guiding devoted bhaktas across the "ocean of existence" (Bhavasagar) and helping them overcome physical, mental, and divine miseries. By witnessing a devotee's faith, the Guru places Knowledge (Samvitti) in their hands and grants liberation (Moksha) effortlessly, thereby destroying the cycle of worldly existence (Samsara).
