What is the relationship between the physical body and death according to Sai's teachings?

Chapter 43 teaches that death is intrinsically linked to the physical body, not the true self. It defines birth as the 'union of body and senses' and death as the 'separation of body and senses.' Death is explicitly called the 'nature of the body' and, poetically, a 'state of happiness for the body.' Life is seen as a modification of the body. For saints who transcend body-consciousness, the body is merely an adjunct, and they are not affected by its physical or mental states. The text emphasizes that one who has spiritually 'turned the body to ashes' even before it falls has no fear of death.
