Chapter 46 defines several key spiritual concepts like 'Dharma', 'Knowledge', and 'Detachment'. Can you elaborate on these definitions and their interconnectedness as presented in the text?

Chapter 46 offers a unique, Guru-centric perspective on fundamental spiritual terms. It defines 'Dharma' not as a set of external rules, but as loving devotion to the Guru. The secret of 'Knowledge' is revealed as the realization of unity, expressed as 'all this is Me'. 'Detachment' is defined as a supreme aversion to worldly objects. These concepts are deeply intertwined; the chapter suggests that sincere devotion (Dharma) purifies the mind, which allows for the dawning of true Knowledge and, consequently, a natural Detachment from the mundane. It asserts that for one who has such devotion, Peace, Detachment, and Fame are always under their control.
