Why was it so hard to define Sai Baba's religious identity as either Hindu or Muslim based on the details in Chapter 7?

Chapter 7 illustrates that Sai Baba's identity was a holy paradox, making it impossible to categorize him as solely Hindu or Muslim. If called a Hindu, he looked like a Muslim and lived in a mosque. If called a Muslim, he had pierced ears like a Hindu, and the mosque he lived in contained a constantly burning sacred fire (Dhuni). Furthermore, this mosque saw Hindu practices like the ringing of bells and blowing of conches. As Chapter 7 states, if called a Hindu, his circumcision was evident, yet if called a Muslim, his ears were pierced. This deliberate ambiguity reinforced that his incarnation was holy and beyond such worldly distinctions.
