What made the mosque where Sai Baba lived so unusual compared to a typical mosque?

According to Chapter 7, the mosque where Sai Baba resided was highly unconventional due to the blend of religious practices He allowed within it. While it was a mosque, it housed a sacred fire (Dhuni) that burned day and night, a practice associated with Hindu ascetics. Furthermore, the chapter describes activities typically found in a Hindu temple occurring there, such as the ringing of bells, the blowing of conches, offerings to the fire, constant devotional singing (Bhajan), and the ritual washing of feet in worship. The presence of a grinding stone for wheat and even a Tulsi Vrindavan, an altar for the holy basil plant sacred to Hindus, made His mosque a unique place that defied religious norms.
