Can you explain the specific definitions of 'Dharma', 'Knowledge', 'Detachment', and 'Cessation' as presented in Chapter 46?

Certainly. Chapter 46 provides concise, devotion-centric definitions for these core spiritual concepts. It defines 'Dharma' not as a set of rules, but simply as "Loving devotion to the Guru." The secret of 'Knowledge' is revealed as the profound realization that "all this is Me," pointing to a non-dual understanding of the self's unity with all of existence. 'Detachment' is defined in its supreme form as an "aversion to worldly objects," which is a natural turning away from sensory attachments. Finally, 'Cessation' (Uparam) is the state where the entanglement in worldly life ceases to be. As per this chapter, these principles are all realized through the central path of devotion to the Guru.
