What does Chapter 10 reveal about the Sadguru's power to influence a devotee's destiny and spiritual progress?

Chapter 10 powerfully illustrates the Sadguru's profound ability to transform a devotee's life and fate. It states that by placing faith in the Guru's feet, He "strikes a nail over the lines of destiny," effectively changing one's fate. For devoted bhaktas, the Sadguru acts as a boatman, helping them cross the three types of miseries and the entire ocean of existence (Bhavasagar). Furthermore, as described in Chapter 10, the Guru's mere sight can break the knots of the heart, eliminate attachment to sense objects, and destroy both accumulated (Sanchit) and current (Kriyaman) karmas, ultimately granting the blissful attainment of liberation.
