Can you describe the specific rituals and preparations involved in Sai Baba's Chavadi procession that made it so special?

The Chavadi procession was a meticulously organized and deeply symbolic event that, according to Chapter 37, began its regular schedule in December 1910. Preparations were extensive: a bhajan group would sing until midnight, and the surroundings were decorated with arches, garlands, and lamps. A key element was the unique relationship between Baba and Tatya Patil; Baba would not leave until Tatya arrived to help Him up. Before departing, Baba performed a specific ritual: He would touch a bundle of firewood with His toe and then extinguish a flame with a wave of His hand. As the procession began, a symphony of musical instruments, horns, trumpets, and fireworks filled the air, creating a truly memorable and divine celebration.
