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

Chapter 46 extols the immense rewards of sincere devotion to the Guru. It states that for those with worldly desires, Sai's name fulfills them, while for the desireless, it grants the "home of self-bliss." The power of such devotion is so great that Peace, Detachment, and Fame are said to always remain under its control. A true devotee, as described in Chapter 46, will obtain whatever they desire in their heart without any effort. The chapter makes the profound claim that even the state of Brahman-realization serves such a devotee like a maid-servant, and they do not even need to ask for liberation, highlighting the supreme status of heartfelt devotion.
