From a philosophical standpoint, how does Chapter 43 deconstruct the reality of birth and death for a Self-realized being?

Chapter 43 posits that for a Self-realized being like Sai Samarth, who is a "mass of bliss," the entire framework of birth and death is illusory. The text argues, "for him who does not know the birth of the body, how can there be death for his body?" This implies that transcendence is achieved by negating the primary identification with the physical form. For such beings, who have already "turned the body to ashes" metaphorically while living, death is like dust before them. As Chapter 43 explains, their existence is not defined by the union or separation of body and senses; they incarnate by their own will for the welfare of devotees, rendering birth and death mere false imaginations within their divine play.
