Chapter 10 makes the bold claim that the Guru can change one's fate. What is required from the devotee for this to happen?

Chapter 10 explains that a Sadguru can "strike a nail over the lines of destiny," meaning he has the power to alter a person's fate. However, this divine intervention is not arbitrary; it is contingent upon the devotee's state of heart and mind. The text emphasizes that the primary requirement is unwavering faith and pure service to the Sadguru. It explicitly contrasts this with intellectual approaches, stating there is "no need for the struggle of logic, Mimamsa, or other intellectual acrobatics." Instead, a devotee must place their trust in the Guru completely, much like one trusts a boatman to cross an ocean. As Chapter 10 clarifies, it is this simple, profound faith and devotion that unlocks the Guru's grace to change destiny.
