From Sai's viewpoint, what is the connection between the physical body, life, and death?

The teachings in Chapter 43 describe death as the natural state and even a state of happiness for the body, while life is considered a modification of the body. The text draws a clear distinction: the union of the body and senses is birth, and their separation is death. For a fully realized being like Sai, who is devoid of bodily impulses and filled with his true form, the consciousness of the body is an illusion. Therefore, physical life and death are irrelevant to his true, eternal nature, which is the Supreme Brahman.
