According to the Satcharitra, what is the power and importance of a Guru's grace in a devotee's life?

Based on Chapter 45, the Guru's power is immense and transformative. The text states that the Guru's feet are even more powerful than Moksha, or liberation, which is considered the supreme goal of human life. By serving the holy water of the Guru's feet, liberation can enter one's home without them even realizing it. The chapter further explains that when a Guru becomes merciful, worldly life becomes happy, the impossible becomes possible, and the Guru can guide a devotee across the ocean of worldly existence in a single moment.
