How did the Chavadi celebration start, and what were the key elements of the devotional gathering?

The Chavadi celebration began on December 10, 1910, establishing a rule where Baba would spend alternate nights there. As described in Chapter 37, on the designated night, a bhajan group would assemble in the Masjid's pavilion. Devotees, both men and women, would eagerly participate, using instruments like cymbals, wooden clappers, mridanga drums, and tambourines to create a 'storm of bhajan.' The scene was set with Baba seated in the middle, a chariot behind Him, and a Tulsi altar to the side, creating a powerful devotional focus for all the devotees who were drawn to Him like iron to a magnet.
