The text says Baba lived in a mosque. What Hindu-style activities and objects were present there that made it so unusual?

According to Chapter 7, Sai Baba's mosque was highly unusual because it incorporated many elements typically associated with Hindu worship. A sacred fire, or Dhuni, burned there day and night. The sounds of bells ringing and conches blowing, both common in Hindu temples, could be heard in the mosque. Furthermore, the chapter mentions the grinding of grain, offerings to the fire, constant bhajans (devotional songs), and even the ritual washing of feet and worship taking place within its walls. In the assembly hall, there was also a specially made Tulsi Vrindavan, an altar for the holy basil plant, which is sacred in Hinduism. These practices made it difficult for anyone to classify him strictly as a Muslim.
