Based on Chapter 45, what is the significance of the Guru's feet and mercy?

Chapter 45 of the Shri Sai Satcharitra places profound significance on the Guru, stating that the Guru's feet are even more powerful than Moksha (liberation). The text explains that by serving the holy water from the Guru's feet, liberation can unknowingly enter a devotee's home. It emphasizes that if the Guru becomes merciful, worldly life becomes happy, seemingly impossible things become possible, and the Guru can guide a person across the ocean of worldly existence in an instant. This highlights the supreme power and grace of the Guru as detailed in Chapter 45.
