How does Chapter 10 explain Sai Baba's power over a person's fate and karma?

Chapter 10 powerfully illustrates the Sadguru's ability to influence a devotee's life path. It makes the bold claim that by placing faith in the Guru's feet, He "strikes a nail over the lines of destiny," which is a direct assertion that He can change one's fate. The chapter also addresses His power over karma, stating that by His mere sight, a devotee's accumulated (Sanchit) and current (Kriyaman) karmas are destroyed. This indicates that devotion to the Guru can effectively erase the karmic slate, freeing the individual from the consequences of past and present actions, a profound power attributed to Him in this text.
