What is the philosophical stance of Chapter 10 on the role of the Guru compared to other gods?

Chapter 10 presents a definitive philosophical position on the supremacy of the Guru. The text explicitly states that "All other gods are illusory; the Guru alone is the one eternal God." This elevates the Sadguru beyond a mere teacher to the ultimate divine principle. It argues that while one might trust a boatman to cross a worldly ocean, one must place trust in the great Guru to cross the vast ocean of existence (Bhavasagar). As described in Chapter 10, pure service to the Sadguru supersedes other spiritual or intellectual paths, as it is the key to completely destroying the worldly existence (Samsara) and attaining liberation, demonstrating his unique and paramount role in a devotee's life.
