Could you explain how Chapter 46 defines the concepts of 'Dharma', 'Knowledge', 'Detachment', and 'Gururpan' in the context of devotion to the Guru?

Chapter 46 provides specific definitions for key spiritual concepts centered on devotion. It defines 'Gururpan' as the complete surrender of the mind at the Guru's feet, a state characterized by an inclination towards peace and devotion. 'Dharma' is equated with loving devotion to the Guru. The secret of 'Knowledge' is described as the profound realization that 'all this is Me,' indicating a non-dual perspective. 'Detachment' is defined as a supreme aversion to worldly objects. This chapter asserts that when devotion is performed with heart and soul, these virtues, along with Peace and Fame, remain under the devotee's control, and even the state of Brahman-realization becomes subservient to such a devotee.
