What does Chapter 46 say about the power of devotion to the Guru and the rewards for a truly devoted person?

Chapter 46 extols the immense power of devotion to the Guru. It teaches that through devotion, one lacks absolutely nothing. For those with worldly desires, their wishes are fulfilled, while the desireless are given the "home of self-bliss." The greatness of such devotion is so profound that, as stated in this chapter, Peace, Detachment, and Fame remain under its control. It goes even further to say that before true devotion, even the state of Brahman-realization serves like a maid-servant, and liberation is not even sought after. This highlights that loving devotion to the Guru, performed with heart and soul, is the supreme path to obtaining anything one desires without effort.
