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

Tatya Patil shared a very close and loving relationship with Sai Baba, so much so that he affectionately called Baba 'Mama' (uncle). Chapter 37 highlights his crucial role in the Chavadi procession. Baba would wait specifically for Tatya to arrive before leaving the Masjid. Tatya would then place his hand under Baba's arm to help Him stand, place a golden-bordered shawl over Him, and hold His left hand throughout the walk to the Chavadi. This illustrates the deep mutual love and importance of Tatya in Baba's routine.
