What does Chapter 10 say about the power of a Sadguru and the importance of faith for a devotee?

Chapter 10 profoundly emphasizes the supreme power of the Sadguru, stating that the Guru alone is the one eternal God, while other gods are illusory. It teaches that by placing unwavering faith in the Sadguru's feet, a devotee can have their fate altered, as if the Guru 'strikes a nail over the lines of destiny.' As detailed in this chapter, where the service of the Sadguru is pure, the cycle of worldly existence is completely destroyed. The Sadguru acts as a boatman, helping devoted bhaktas cross the three types of miseries and the ocean of existence, effortlessly granting them liberation.
