If death is a separation from the body, why is it described as a 'state of happiness for the body'?

The texts in Chapter 43 present a perspective where death is not a sorrowful event but the natural state for the physical form. It is described as a 'state of happiness for the body' because the body's end is its natural course, free from grief. Life, in contrast, is called a 'modification of the body.' For a being like Sai Samarth, who is a 'mass of bliss' and does not know the birth of the body in the conventional sense, there can be no death for his body. He is devoid of bodily impulses, existing as the complete Supreme Brahman.
