How does Chapter 10 describe the power of the Guru, Sai Baba, to influence a devotee's life and destiny?

According to Chapter 10 of the Shri Sai Satcharitra, the Guru's power is absolute and transformative. The text asserts that while other gods are illusory, the Guru is the "one eternal God" who can alter a person's fate, a concept described as striking "a nail over the lines of destiny." By having faith in the Sadguru, a devotee can overcome the three types of miseries and be ferried across the ocean of worldly existence. Furthermore, the chapter explains that the Guru's sight alone can destroy a devotee's accumulated (Sanchit) and current (Kriyaman) karmas, remove attachments, and grant the ultimate liberation (Moksha) effortlessly.
