What was the specific and indispensable role of Tatya Patil during the Chavadi procession?

Tatya Patil played a uniquely intimate and crucial role in the Chavadi procession. Chapter 37 highlights that Sai Baba would not begin His walk to the Chavadi until Tatya Patil arrived. It was Tatya who would place his hand under Baba's arm to help Him stand up. Furthermore, Tatya would lovingly place a beautiful golden-bordered shawl over Baba's head and shoulders. Their bond was so profound that Tatya affectionately called Baba 'Mama,' and the text states their close relationship was beyond comparison, underscoring Tatya's essential presence in this sacred ritual.
