How did the Chavadi procession officially commence, and what was Tatya Patil's role?

The commencement of the Chavadi procession was entirely dependent on the arrival and actions of Tatya Patil. As detailed in Chapter 37, even if Sai Baba was ready, He would remain seated and wait for Tatya. Only when Tatya Patil, who affectionately called Baba 'Mama', arrived and put his hand under Baba's arm to help Him up would Baba prepare to leave. Tatya would then place a beautiful golden-bordered shawl over Baba's head. This unique and close relationship highlights that the procession could not start until Tatya initiated this specific, loving gesture.
