How did Sai Baba's physical appearance and personal customs make it impossible to classify him as either Hindu or Muslim?

According to Chapter 7, Sai Baba embodied a paradox that defied religious categorization. The text states that if you called him a Hindu, he looked like a Yavana (Muslim), but if you called him a Yavana, he bore the noble marks of a Hindu. This ambiguity was physical as well as spiritual; the chapter notes that his ears were pierced, a common Hindu custom, while there was also evidence of circumcision, a Muslim practice. This made it so that not an atom's worth of a trace could be found to definitively place him in either community.
