What is the distinction made in Chapter 43 between death for an ordinary person and death for an enlightened soul?

Chapter 43 draws a sharp distinction between the two. For an ordinary person, death is defined as the 'separation of body and senses,' an event that is inseparably attached to birth. For an enlightened soul who has 'killed death' and placed their feet 'on the head of Time,' death is a false imagination. The text clarifies that avatars and saints incarnate by their own will for the welfare of devotees and are not bound by this cycle. While death is the nature of the physical body, for a Yogi who has realized their true self, death is like 'dust before him,' and leaving the body is a voluntary act of merging with the unmanifest, not a forced cessation.
