Based on the teachings in Chapter 46, what is the supreme importance of devotion to the Guru, and what are its rewards?

The text of Chapter 46 elevates devotion to the Guru to the highest pedestal. It defines 'Dharma' itself as loving devotion to the Guru. The rewards of such sincere devotion are immense; the chapter states that Peace, Detachment, and Fame remain under the devotee's control. It poses the question, 'what could they possibly lack?' assuring that whatever a true devotee desires, they will obtain without effort. The greatness of this devotion is such that even the state of Brahman-realization is said to serve it like a maid-servant, and liberation is not even sought after, emphasizing that devotion is the ultimate goal and reward in itself.
