What does Chapter 10 say about the role of the Guru and the benefits of having faith in one?

Chapter 10 powerfully states that the Guru is the "one eternal God" while other gods are illusory. It teaches that placing faith in the Sadguru's feet can fundamentally alter one's life, as He can "strike a nail over the lines of destiny," effectively changing fate. The chapter uses the analogy of a boatman, explaining that just as one trusts a boatman to cross a worldly ocean, one must trust the Guru to cross the ocean of existence (Bhavasagar). For devotees with pure faith, the Sadguru helps them overcome all miseries and effortlessly gives them Knowledge (Samvitti) and liberation (Moksha).
