What was Tatya Patil's specific role before Sai Baba would leave for the Chavadi?

Tatya Patil played a uniquely intimate and essential role in the Chavadi procession. Chapter 37 reveals that Sai Baba would not begin His journey to the Chavadi until Tatya arrived. Tatya would approach Baba, lovingly place a hand under His arm to help Him stand, and then place a beautiful golden-bordered shawl over Baba's head, adjusting it properly. This interaction highlights their special bond, with Tatya even calling Baba 'Mama' (uncle), signifying a close relationship for which there is no comparison.
