The book says it's hard to tell if Sai Baba was Hindu or Muslim. What evidence does Chapter 7 provide for this confusion?

Chapter 7 provides extensive evidence for Sai Baba's ambiguous religious identity, making it impossible to categorize him as solely Hindu or Muslim. It states that if called a Hindu, he looked like a Muslim (Yavana), but if called a Muslim, he had the noble marks of a Hindu. Physically, his ears were pierced like a Hindu, yet there was evidence of circumcision. He resided in a mosque, a Muslim practice, but kept a sacred fire (Dhuni) burning there and allowed the ringing of bells and blowing of conches, which are Hindu rituals. As described in Chapter 7, he celebrated the Hindu festival of Ram Navami and the Muslim Sandal procession with equal joy, leading the text to conclude his incarnation was holy and beyond both religions.
