How does the scripture explain the concept of death, and how does this view show that it doesn't apply to Sai Baba?

According to Chapter 43, death is defined as the separation of the body and senses, while birth is their union. For most, this cycle is inseparable. However, this definition does not apply to a being like Sai Baba. The text explains that as Sai Samarth is a "mass of bliss" and the "complete Supreme Brahman," the very ideas of birth and death are irrelevant to him. Since he is devoid of bodily impulses and considers the world an illusion, he lacks the body-consciousness necessary for birth or death to have meaning. Chapter 43 states that for saints, death is merely a "defect of vision," like an eclipse, not a true end.
