According to Chapter 10, how can faith in Sai Baba affect a person's destiny and accumulated karma?

Chapter 10 powerfully asserts that faith in the Sadguru, Sai Baba, can fundamentally alter a person's life path and spiritual balance. The text states that by placing faith in His feet, He "strikes a nail over the lines of destiny," which is interpreted as changing one's fate. Furthermore, the chapter explains the impact on karma. It claims that by His mere sight, the knots of the heart are untied, attachment to sense objects vanishes, and both accumulated (Sanchit) and current (Kriyaman) karmas are destroyed. This profound spiritual cleansing and liberation from the cycle of karma is presented as something the Guru grants effortlessly to his devoted followers.
