According to Chapter 45, what is the impact of a Guru's mercy and the significance of serving them?

Chapter 45 explains that the Guru's feet are considered even more powerful than Moksha, or liberation. By serving the holy water from the Guru's feet, Moksha can unknowingly enter one's home. The chapter further states that if the Guru becomes merciful, worldly life becomes happy, the impossible can become possible, and the Guru can take a devotee across to the other shore in a moment. This highlights the immense power and grace of the Guru as described in the text.
