How does Chapter 45 describe the power and importance of the Guru, specifically in relation to achieving liberation (Moksha)?

Chapter 45 places the Guru's grace above even the ultimate spiritual goal of Moksha, or liberation. The text states that the Guru's feet are even more powerful than Moksha itself. By serving the holy water from the Guru's feet, it is believed that Moksha can enter a devotee's home without them even realizing it. The chapter further emphasizes that it is only through the Guru's mercy that worldly life becomes happy and the impossible can become possible. This grace is what enables the Guru to take a devotee across the metaphorical shore of worldly existence in a single moment, as described in the chapter.
