Can you explain how Chapter 10 describes Sai Baba's power to influence a devotee's karma and fate?

Chapter 10 powerfully asserts that a Sadguru like Sai Baba possesses the ability to completely alter a devotee's destiny and karmic baggage. The text states that by placing faith in His feet, He "strikes a nail over the lines of destiny," which is a direct reference to changing one's fate. Furthermore, the chapter details that the Guru's mere sight can break the knots of the heart and cause all attachments to sense objects to vanish. Most significantly, it claims that both accumulated (Sanchit) and current (Kriyaman) karmas are destroyed through His grace. This shows that devotion to the Sadguru is presented as a path that transcends the laws of karma, offering liberation from past and present actions.
