How does Chapter 46 define key spiritual concepts like Dharma, Knowledge, and Detachment in the context of devotion to a Guru?

In Chapter 46, the text provides concise definitions for fundamental spiritual concepts. It states that loving devotion to the Guru is itself called 'Dharma' (righteousness). The secret of 'Knowledge' is understanding that 'all this is Me,' implying a recognition of the divine unity in all creation. 'Detachment' is defined as a supreme aversion to worldly objects and sensory pleasures. Where these three—Dharma, Knowledge, and Detachment—converge through devotion, the 'Cessation' (Uparam) of the worldly cycle of life and death occurs. This chapter frames these concepts not as abstract philosophies but as direct experiences realized through surrender to the Guru.
