According to Chapter 10, what is the significance of placing faith in the Guru, and how does this relate to one's destiny and karma?

Chapter 10 profoundly states that the Guru is the one eternal God, and placing pure faith in him has a transformative power over a devotee's life. It makes the powerful claim that by trusting the Sadguru, he "strikes a nail over the lines of destiny," which means he can change one's fate. The chapter explains that with the Guru as a boatman, devotees can cross the ocean of worldly existence. Furthermore, the Guru's sight can break the knots of the heart, eliminate attachments, and even destroy accumulated (Sanchit) and current (Kriyaman) karmas, ultimately granting the effortless attainment of liberation.
