Based on Chapter 7, what were the contradictory signs regarding Sai Baba's religious identity that puzzled his followers?

Chapter 7 delves into the enigmatic nature of Sai Baba's religious affiliation by presenting a series of paradoxes. It states that if one called him a Hindu, he appeared like a Muslim (Yavana), but if called a Muslim, he bore the noble marks of a Hindu. The text points to conflicting evidence: he resided in a mosque, yet a sacred fire (Dhuni) burned there constantly, and Hindu rituals like the ringing of bells, blowing of conches, and offering to fire took place. Conversely, if one considered him a Hindu, the text notes his circumcision was evident, while his pierced ears suggested a Hindu background. This left people unable to find even an atom's worth of a trace of his true caste.
