Can you explain the philosophical perspective on birth and death presented in the text, especially concerning Sai Baba's divine nature?

Chapter 43 provides a deep philosophical perspective, defining birth as the 'union of body and senses' and death as their 'separation.' It posits that death is an inherent characteristic of the soul's nature. However, for divine avatars like Sai Baba who incarnate by their own will 'for the welfare of devotees,' these concepts are dismissed as 'false imaginations.' The text elevates Sai to the status of the 'complete Supreme Brahman,' for whom the world is an illusion and bodily consciousness is non-existent. Consequently, the very notions of birth and death are inapplicable to him. His actions are described as a 'spontaneous play of Yoga' for the salvation of his followers, not events governed by mortal laws.
