According to Chapter 45, what is the role of the Guru and how does it relate to liberation?

Chapter 45 explains that the Guru's role is paramount, even more so than the pursuit of Moksha, or liberation. The text states that by serving the "holy water of the Guru’s feet, Moksha unknowingly enters one’s home." This highlights the immense power and grace of the Guru. As mentioned in the chapter, if the Guru becomes merciful, life becomes happy, the impossible becomes possible, and He can guide a devotee across the challenges of worldly existence in an instant. This profound significance of the Guru is a central theme introduced at the beginning of Chapter 45.
