How does Chapter 10 explain Sai Baba's power to influence a devotee's destiny and karma?

Chapter 10 elaborates on the Sadguru's profound ability to alter a devotee's life path. It famously states that by placing faith in the Guru's feet, He "strikes a nail over the lines of destiny," which is interpreted as changing one's fate. Furthermore, the chapter explains that by His mere sight, the knots of the heart are broken and attachments vanish. Most significantly, it claims that both accumulated (Sanchit) and current (Kriyaman) karmas are destroyed for the devoted bhakta, highlighting the Guru's power to completely absolve a follower's karmic baggage.
