What does Chapter 10 explain about the role of a Sadguru and the benefits a devotee receives from having faith?

Chapter 10 powerfully illustrates the role of the Sadguru, presenting the Guru as the "one eternal God" in contrast to other illusory gods. By placing faith in the Sadguru's feet, a devotee can have their destiny changed, as the text poetically states He "strikes a nail over the lines of destiny." The chapter further explains that the Sadguru acts as a boatman, helping devoted bhaktas cross the three types of miseries and the vast ocean of worldly existence (Bhavasagar). In response to a devotee's faith, the Guru places Knowledge (Samvitti) in their palm and grants the attainment of liberation (Moksha) effortlessly.
