According to Chapter 10, what is the role of a Sadguru and what can someone gain by having faith in them?

Chapter 10 of the Shri Sai Satcharitra explains that the Sadguru is paramount, described as the "one eternal God" who can change a devotee's fate. By placing faith in the Guru's feet, one can overcome the three types of miseries and cross the ocean of existence (Bhavasagar). The text states that when a Sadguru sees the devotion and faith of their followers, He grants them Knowledge (Samvitti) and the attainment of liberation (Moksha) effortlessly. This service to the Guru is portrayed as a path that destroys worldly existence (Samsara) without the need for complex intellectual struggles.
