How does Chapter 5 explain the actions of a wise person and their relationship with karma and duality?

In Chapter 5, the text explains that the bodily activities of a wise person occur according to their previous karma, but they are not the doer of these actions nor are they burdened by them. A wise individual resides in a state of non-duality. The chapter uses a powerful analogy to describe this state: 'Only if the sun were to enter darkness would a wise man have the sense of duality.' This is because for such a person, their own form is the entire universe, and they exist completely within the realm of non-duality. This profound teaching from the fifth chapter highlights the detached and enlightened perspective of a truly wise soul.
