It sounds like the Chavadi procession was a huge spectacle. Who were the key people physically assisting Sai Baba, and what exactly were their roles during the walk?

The Chavadi procession, while a grand and joyous event with a large crowd, was quite organized around Sai Baba's personal escort. Chapter 37 specifies the exact roles of His closest devotees who walked with Him. Tatyaba Patil, who shared a deep, loving bond with Baba, would hold His left hand, while Mhalasapati held His right hand. To provide shade and honor, Bapusaheb Jog held an umbrella over Baba's head. Furthermore, two chowrie-bearers walked on either side, fanning Him with fans. This shows a structured and respectful escort ensuring Baba's comfort during the procession from the Masjid to the Chavadi.
