What does Chapter 46 say about the power of devotion to the Guru, and what rewards does it bring?

Chapter 46 extols the supreme greatness of devotion to the Guru, stating that a devotee with such a disposition will lack nothing. It promises that whatever they desire in their heart, they will obtain without any effort. The power of this devotion is so immense that, as the chapter describes, even the state of Brahman-realization serves it like a maid-servant, and liberation is not something that needs to be asked for. True devotion, performed with heart and soul, ensures that Peace and Detachment remain constantly under the devotee's control, signifying a complete and fulfilled spiritual life.
