According to the teachings in Chapter 45, what specific benefits are gained from serving the Guru?

Chapter 45 extols the immense benefits of serving the Guru, placing it above all other spiritual goals. The chapter explicitly states that the Guru's feet are even 'more powerful than Moksha (liberation).' By devoutly serving the holy water from the Guru’s feet, Moksha is said to enter one’s home unknowingly. Furthermore, Chapter 45 teaches that when the Guru becomes merciful, one's worldly life becomes happy, the impossible becomes possible, and the Guru can instantly take a devotee across the ocean of worldly existence to the other shore.
