How does Sai Baba's nature as being 'subservient to his devotees' continue even after he left his physical body?

Chapter 48 of the Sai Satcharitra elaborates on this unique quality of Sai Baba. It describes him as one who, seeing the pure love of his followers, acts as 'subservient to his devotees.' This is presented as his sacred vow. The text clarifies that this quality did not cease with his physical life. It explicitly states that his role as a benefactor to his devotees does not end even after leaving the body and merging with the Unmanifest. The profound assurance given in Chapter 48 is that the very same actions and experiences of grace that were performed while he was in his body are still experienced today in his Unmanifest state by those who are truly devoted to him.
