What was the specific role of Tatya Patil in the Chavadi procession, and how was his relationship with Baba described?

Chapter 37 highlights the uniquely close relationship between Sai Baba and Tatya Patil. Baba would not begin His journey to the Chavadi until Tatya arrived. It was Tatya who would put his hand under Baba's arm to help Him stand, signaling the moment of departure. Tatya affectionately called Baba 'Mama' (uncle), and their mutual love was described as a close relationship for which there is no comparison. Tatya would also place a beautiful golden-bordered shawl over Baba, further underscoring his intimate and essential role in the proceedings.
