What does it mean when the text calls Sai Baba the 'complete Supreme Brahman' and how does that relate to birth and death?

Calling Sai Baba the 'complete Supreme Brahman' identifies him with the ultimate, formless, and eternal reality in Hindu philosophy. As Chapter 43 explains, birth and death are phenomena associated with the physical body—the union and separation of body and senses. However, for the Supreme Brahman, which is inherently 'devoid of bodily impulses,' these concepts are inapplicable. From the perspective of Brahman, the material world is an illusion. Therefore, for a being who is one with Brahman, like Sai Baba, there can be no real birth or death. These events are viewed as 'false imaginations' that do not touch his true nature. His apparent passing was simply a yogic act of returning to his unmanifest state.
