Chapter 7 describes Sai Baba's identity as ambiguous. Can you elaborate on the specific details that made it difficult to classify him as either Hindu or Muslim?

Chapter 7 provides several details that illustrate the ambiguity of Sai Baba's religious identity, making him seem beyond such classifications. The text states that if you called him a Hindu, he looked like a Yavana (Muslim), and if you called him a Yavana, he bore the noble marks of a Hindu. More specifically, as mentioned in Chapter 7, he had contradictory physical signs: his ears were pierced, a common Hindu practice, yet there was also evidence of circumcision. Furthermore, if one considered him a Hindu, his constant residence in a mosque was a significant contradiction. This holy incarnation was thus considered beyond the simple labels of Hindu or Muslim.
