Based on Chapter 7, what Hindu religious activities surprisingly took place in the mosque where Sai Baba lived?

Chapter 7 explains that Sai Baba's residence, a mosque, was paradoxically the site of numerous Hindu rituals, which confounded visitors. The text highlights that a sacred fire, or Dhuni, burnt there day and night. The mosque also saw the ringing of bells and blowing of conches, constant Bhajan (devotional singing), offerings to the fire, and even the ritual washing of feet and worship. These practices, so integral to Hindu temple worship, made it difficult for anyone to definitively label Him a Muslim, despite His choice of dwelling.
