What was Tatya Patil's specific and personal role in getting Baba ready for the Chavadi procession?

Tatya Patil had a uniquely intimate and essential role in the Chavadi procession. According to Chapter 37, Sai Baba would not leave the Masjid until Tatya arrived, demonstrating their close bond. Tatya, who affectionately called Baba 'Mama', would initiate the departure by placing his hand under Baba's arm and helping Him to stand. Following this, Tatya would place a beautiful golden-bordered shawl over Baba and adjust it properly on His head. During the procession itself, Tatyaba held Baba's left hand, guiding Him along the path. Their relationship was so cherished that the text notes there is no comparison to give for their closeness.
