How does Chapter 46 define the concepts of 'Dharma', 'Knowledge', and 'Detachment' from the perspective of Guru devotion?

In a profound set of verses, Chapter 46 offers specific definitions for key spiritual concepts, framing them entirely around devotion to the Guru. It defines 'Dharma' simply as loving devotion to the Guru. The secret of 'Knowledge' is explained as the realization that 'all this is Me,' pointing towards a non-dual understanding. Supreme 'Detachment' is described as having an aversion to worldly objects and pursuits. The chapter concludes this line of teaching by stating that where these three—Dharma, Knowledge, and Detachment—are present through Guru devotion, the 'Cessation' (Uparam) of the cycle of worldly life naturally occurs.
