What is the philosophical understanding of birth and death presented in this chapter, especially in relation to a saint like Sai Baba?

The text defines birth as the union of the body and senses, and death as their separation. However, for a fully realized being like Sai Baba, these concepts are considered false imaginations. According to chapter 43, Sai is the complete Supreme Brahman, for whom bodily consciousness is an illusion. Death for saints is compared to a solar eclipse—a mere defect of vision, not a true end. Since Sai Baba is described as a "mass of bliss" who does not know the birth of a body, the concept of death for his body is rendered meaningless. He is beyond such physical limitations and modifications.
