What philosophical distinction is made between the life and death of an ordinary person versus a saint?

Chapter 43 draws a sharp philosophical distinction. For an ordinary person, birth is the "union of body and senses" and death is their "separation," an inseparable pair that defines existence. However, for a saint who has realized their true nature, this duality is meaningless. The text states that a saint has already "turned the body to ashes" even before it falls, meaning they have completely overcome identification with their physical form. While life is a "modification of the body," a saint like Sai is a "mass of bliss" and the Supreme Brahman, devoid of bodily impulses. As chapter 43 explains, death is the nature of the body, but for a saint, it is a state of happiness or simply irrelevant, as they have placed their "feet on the head of Time."
