According to Chapter 7, why was it so difficult to determine if Sai Baba was Hindu or Muslim?

Chapter 7 of the Shri Sai Satcharitra explains that Sai Baba's identity was a profound paradox. The text states that if he was called a Hindu, he looked like a Yavana (Muslim), and if called a Yavana, he had the noble marks of a Hindu. This ambiguity was so complete that the author notes not "an atom’s worth of trace could be found" to establish his origins. The chapter further highlights this contradiction by pointing out that he had pierced ears, a Hindu custom, yet his circumcision was also evident. He resided in a mosque, but it was filled with Hindu practices, making him a holy incarnation beyond any single religious classification.
