The text says Baba lived in a mosque. What Hindu-style practices occurred there that made his identity so ambiguous?

According to Chapter 7, although Sai Baba resided in a mosque, many activities traditionally associated with Hindu temples took place there, creating a profound sense of ambiguity about his religious affiliation. The chapter explicitly states that a sacred fire, or Dhuni, burned day and night within the mosque. Furthermore, the sounds of bells ringing and conches blowing, common in Hindu worship, were heard. The text also mentions the grinding of grain, constant Bhajan (devotional singing), offerings to the fire, and the ritual washing of feet for worship, all taking place in the mosque, making observers question how he could be a conventional Muslim.
