What is the book's philosophical take on birth and death, especially concerning saints like Sai Baba?

The text explains that birth is the union of the body and senses, while death is their separation. However, for great souls and avatars like Sai Baba, these concepts are considered false imaginations. As detailed in Chapter 43, death is a characteristic of the physical body, not the soul. Since Sai Baba is described as the complete Supreme Brahman, for whom the world is an illusion, he is devoid of bodily impulses and the consciousness of the body. Therefore, the conventional notions of birth and death do not apply to him, as he incarnates by his own will for the welfare of his devotees.
