When did formal worship begin at the Chavadi and what did it entail?

According to the source material in Chapter 37, the formal practice of worship, bhajan, and adoration of Sai Baba at the Chavadi began on December 10, 1910. This marked a formalization of the location's spiritual importance. On the nights designated for the Chavadi, a bhajan group would assemble at the Masjid and perform until midnight. Devotees, both men and women, would gather with instruments to create a powerful and devotional musical atmosphere. This new phase of activity at the Chavadi, as described in Chapter 37, signifies a key development in the collective worship practices of Sai Baba's followers.
