Can you explain the concepts of 'Dharma', 'Knowledge', and 'Detachment' as they relate to devotion to the Guru in Chapter 46?

Chapter 46 offers specific definitions for these profound concepts within the context of devotion to a Guru. It defines 'Dharma' simply as loving devotion to the Guru. 'Knowledge' is described as understanding the secret that 'all this is Me,' implying a non-dual realization. 'Detachment' is characterized as a supreme aversion to worldly objects. The chapter emphasizes the greatness of such devotion, stating that when performed with heart and soul, it brings Peace, Detachment, and Fame under its control, and before it, even the state of Brahman-realization serves like a maid-servant.
