What contradictory physical signs and life choices made it impossible to label Sai Baba as strictly Hindu or Muslim?

Chapter 7 delves into the profound mystery of Sai Baba's identity, presenting a series of paradoxes that defied religious classification. The text notes that if you called him a Hindu, he appeared like a Yavana (Muslim), yet if you called him a Yavana, he bore the noble marks of a Hindu. Physically, it mentions that his ears were pierced in the Hindu tradition, but his circumcision was also evident, a Muslim practice. Furthermore, he resided his entire life in a mosque, a Muslim place of worship, but within that mosque, he maintained a sacred Hindu fire (Dhuni) and allowed bells and conches to be sounded, making his true origin an unsolvable puzzle.
