The text says Sai Baba is the 'complete Supreme Brahman.' How does this relate to the idea that he is beyond birth and death?

The Satcharita explains that because Sai Samarth is the 'complete Supreme Brahman' and a 'mass of bliss,' the concepts of physical birth and death do not apply to him. As Chapter 43 clarifies, from the ultimate truth of Brahman, the world is an illusion, and therefore, consciousness of the body is non-existent for such a being. He is described as being devoid of bodily impulses. The text argues that if one does not even know the birth of the body, how can there be death for that body? Therefore, his physical existence and its apparent end are seen as a spontaneous play of Yoga for the salvation of devotees, not a true birth or death.
