How does Chapter 7 illustrate that Sai Baba transcended the classifications of Hindu and Muslim?

Chapter 7 provides numerous examples to show that Sai Baba was beyond any single religious identity. It states that if you called him a Hindu, he looked like a Yavana (Muslim), but if you called him a Muslim, he had the noble marks of a Hindu. More concretely, the chapter points out contradictions like his pierced ears (a Hindu custom) versus his evident circumcision. He resided in a mosque, yet maintained a constantly burning sacred fire (Dhuni), allowed the ringing of bells and blowing of conches, and had a Tulsi Vrindavan, all of which are Hindu practices. Chapter 7 concludes that Sai Baba's incarnation was holy and beyond both classifications, as no definitive trace of him belonging to either group could be found.
