Who were the key people accompanying Sai Baba in the procession, and what were their roles?

Several key individuals had specific roles in accompanying Sai Baba during the Chavadi procession. Chapter 37 explains that Tatyaba Patil held Baba's left hand, while Mhalasapati held His right hand, guiding Him along the path. Bapusaheb Jog had the duty of holding an umbrella over Baba's head. Additionally, two chowrie-bearers walked on either side, fanning Him with fans. A mace-bearer walked in front shouting Sai's name, and heralds would call out as the procession moved, all contributing to the grand and devotional event.
