What was Tatya Patil's role in the Chavadi procession and how is his relationship with Sai Baba described?

Tatya Patil played an indispensable and intimate role in the Chavadi procession. According to Chapter 37, Sai Baba would not even begin to leave the Masjid until Tatya arrived. Tatya would then initiate the departure by putting his hand under Baba's arm and raising Him up. He would also lovingly place a golden-bordered shawl over Baba. Their bond was exceptionally close, as evidenced by Tatya affectionately calling Baba 'Mama' (uncle). The text states there is no comparison to give for their relationship. During the procession itself, Tatya held Baba's left hand as they walked to the Chavadi, signifying his constant and supportive presence.
