What does Chapter 10 teach about the power of a Sadguru and the benefits of having faith in one?

Chapter 10 explains that a Sadguru is the "one eternal God" and that placing faith in His feet can change one's destiny, an act described as "striking a nail over the lines of destiny." The Sadguru serves as a boatman, guiding devoted followers across the ocean of worldly existence (Bhavasagar) and helping them overcome physical, mental, and divine miseries. The text states that for those with pure devotion, the Sadguru can destroy their worldly existence (Samsara), grant Knowledge (Samvitti), and bestow the attainment of liberation (Moksha) effortlessly, highlighting the immense spiritual benefit of surrendering to a true Guru.
