Based on Chapter 46, what defines true devotion to the Guru and what rewards does it bring?

Chapter 46 provides a profound definition of devotion, equating loving devotion to the Guru with 'Dharma' itself. A key sign that a seeker's mind is surrendered at Sai's feet is that they become inclined towards peace and thrive in complete devotion. The chapter extols the greatness of such devotion, claiming that if it is performed with heart and soul, the virtues of Peace, Detachment, and Fame will always remain under the devotee's control. It poses the rhetorical question, "One who has such devotion to the Guru, what could they possibly lack?" promising that they will obtain whatever they desire without effort. The text elevates this state by asserting that even Brahman-realization serves such a devotee like a maid-servant (Chapter 46).
