What was the Chavadi procession like, and when did this specific celebration begin?

The Chavadi procession was a grand celebration that began in a more formal way from December 10th, 1910. As detailed in Chapter 37, Sai Baba would sleep at the Chavadi on alternate nights. On these occasions, a bhajan group would gather at the Masjid and sing until midnight. The area would be festively decorated with arches, flags, and rows of lamps. The procession itself was a vibrant affair with musical instruments, fireworks, and torches, creating a divine atmosphere as Baba made His way from the Masjid to the Chavadi.
