How does Chapter 10 explain Sai Baba's ability to affect a person's karma?

Chapter 10 teaches that the Sadguru holds the power to alter a devotee's karmic state. The text explicitly states that by the mere sight of the Guru, a devotee's accumulated (Sanchit) and current (Kriyaman) karmas are destroyed. This profound effect is a direct result of the Guru's grace, which is bestowed upon those who approach with faith and devotion. This process also involves the breaking of the "knots of the heart" and the vanishing of all attachment to sense objects, which are key elements in breaking free from the cycle of karma and rebirth.
