How does Chapter 10 describe Sai Baba's power over a devotee's destiny?

Chapter 10 of the Shri Sai Satcharitra explains that Sai Baba has the profound ability to alter a person's fate. The text beautifully states that by placing unwavering faith in His feet, He 'strikes a nail over the lines of destiny.' This metaphor illustrates that sincere service and devotion to the Sadguru can completely destroy the worldly existence (Samsara) and its associated miseries. The chapter emphasizes that through His grace, devotees can overcome their predetermined path and attain liberation, a state of bliss, effortlessly, as He places Knowledge in the palm of their hands.
