Based on Chapter 7, how was Sai Baba perceived by his followers, and why was it difficult for anyone to fully comprehend his nature?

As described in Chapter 7, Sai Baba was perceived as an extraordinary and holy incarnation whose true nature was beyond full comprehension. His ambiguous identity was a source of wonder; he appeared as a Muslim to those who called him Hindu and vice versa. Despite living in a mosque, the most revered Brahmins and keepers of sacred fires would abandon their pride and prostrate before him. The text states that people were amazed in their hearts, and those who came to find proof of his identity would become silent and humble in his presence, unable to categorize this extraordinary being.
