Can you explain the relationship between the Guru, Moksha (liberation), and worldly life as described in Chapter 45?

Chapter 45 presents a profound relationship between the Guru, liberation, and worldly happiness. It makes the extraordinary claim that the Guru's feet are "even more powerful than Moksha," the supreme goal of liberation. By serving the holy water from the Guru's feet, Moksha is said to enter one's home unknowingly. The chapter also connects the Guru's grace directly to daily life, stating that "If the Guru becomes merciful, then only does this worldly life become happy." This suggests that devotion to the Guru not only leads to ultimate spiritual goals but also transforms one's present existence.
