Can you explain the supreme power of devotion to the Guru as described in Chapter 46?

Chapter 46 extols the immense power of loving devotion to the Guru, calling it 'Dharma.' It asserts that if a devotee performs this devotion with heart and soul, they will gain control over Peace, Detachment, and Fame. The chapter makes a remarkable claim that a person with such devotion will lack nothing and will obtain any desire of their heart without effort. The greatness of this devotion is such that, as stated in Chapter 46, the state of Brahman-realization serves the devotee like a maid-servant, liberation is not even sought, and holy pilgrimages come to touch their feet.
