What are the ultimate rewards and powers of having true devotion to the Guru, as explained in Chapter 46?

Chapter 46 extols the supreme power of devotion to the Guru, stating that it brings Peace, Detachment, and Fame under the devotee's control. It asserts that a true devotee lacks nothing and will effortlessly obtain whatever they desire in their heart. The greatness of this devotion is so profound that, as Chapter 46 describes, even the state of Brahman-realization acts like its 'maid-servant.' In this elevated state of devotion, one does not even ask for liberation, and holy pilgrimages are said to metaphorically come and touch the feet of such a devotee.
