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

Chapter 45 presents a unique hierarchy of spiritual goals, placing the Guru's grace above all else. It states that the Guru’s feet are "even more powerful than Moksha (liberation), the supreme goal of man." Instead of being a distant goal to be striven for, the chapter suggests that by serving the Guru, "Moksha unknowingly enters one’s home." Furthermore, the text explains that the Guru's mercy is what makes worldly life happy and helps a devotee transcend its challenges, taking them "across to the other shore in a moment." This indicates that devotion to the Guru is the key that unlocks both worldly happiness and ultimate liberation.
