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

Chapter 45 of the Shri Sai Satcharitra places immense importance on the Guru. It states that the Guru's feet are even more powerful than Moksha, or liberation, which is considered the supreme goal of human life. The chapter elaborates that by serving the holy water from the Guru’s feet, Moksha can unknowingly enter a devotee's home. Furthermore, as mentioned in Chapter 45, it is only through the Guru's mercy that worldly life becomes happy, the impossible can become possible, and a devotee can be taken "across to the other shore in a moment," signifying a rapid spiritual and worldly transformation.
