Based on the details in Chapter 7, how did Sai Baba's physical appearance and personal history contribute to the mystery of his religious identity?

Chapter 7 delves into the physical and historical details that made Sai Baba's religious identity a profound mystery. The text notes that if one were to call him a Hindu, he looked like a Yavana (Muslim), but if called a Muslim, he possessed the noble marks of a Hindu. More specifically, the chapter points out two conflicting physical signs: his ears were pierced, a common Hindu custom, but there was also evidence of circumcision, a Muslim practice. This made it impossible to determine his origins, leading the author of Chapter 7 to conclude that Sai's incarnation was holy and beyond both Hindu and Muslim classifications.
