According to Chapter 10, what are the benefits of placing one's faith in a Sadguru like Sai Baba?

Chapter 10 eloquently details the profound benefits of devotion to a Sadguru. It teaches that by placing faith in the Guru's feet, one's destiny can be changed, as if He "strikes a nail over the lines of destiny." As the chapter explains, pure service to the Sadguru completely destroys the worldly existence (Samsara) and helps devotees overcome physical, mental, and divine miseries. Furthermore, the Sadguru grants Knowledge and liberation (Moksha) effortlessly to those with sincere devotion and faith, breaking the knots of the heart and destroying accumulated and current karmas.
