Describe the general atmosphere and the activities that took place at the Masjid on the nights of the Chavadi procession.

According to Chapter 37, the atmosphere at the Masjid on Chavadi nights was filled with devotional celebration. A bhajan group would come to the Masjid and perform in the pavilion until midnight. Baba would be seated in the middle, with a chariot behind him and a Tulsi altar to his right, surrounded by devotees. Men and women would gather, playing instruments like cymbals, wooden clappers, mridanga, and tambourines, creating a 'storm of bhajan'. The text describes Sai as a powerful magnet, drawing his 'iron-like devotees' to his feet with his power.
