How did Sai Baba's life and practices blur the lines between Hindu and Muslim traditions?

According to Chapter 7 of the Shri Sai Satcharitra, Sai Baba's very existence was a paradox that defied religious categorization. If called a Hindu, he looked like a Yavana (Muslim), and if called a Yavana, he bore the noble marks of a Hindu. This ambiguity was reflected in his actions; for instance, he resided in a mosque, a Muslim practice, yet he maintained a constantly burning sacred fire (Dhuni) and allowed the ringing of bells, which are Hindu customs. The text further highlights physical contradictions, noting that while his ears were pierced like a Hindu's, his circumcision was also evident. Ultimately, Chapter 7 concludes that he was a holy incarnation beyond the labels of Hindu or Muslim, treating both groups with equal regard.
