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

Chapter 46 of the Sai Satcharitra extols the immense power of true devotion. A key sign that one's mind is surrendered at Sai's feet is that the seeker becomes inclined towards peace and thrives in complete devotion. The rewards are boundless: such a devotee is said to lack nothing and will obtain whatever they desire in their heart without effort. The chapter makes a powerful claim that before such devotion, even the exalted state of Brahman-realization serves like a maid-servant, and liberation is not something that needs to be asked for. This illustrates that complete devotion to the Guru is the highest attainment.
