What was the nature of the relationship between Tatya Patil and Sai Baba, and how was this reflected in Tatya's role during the Chavadi procession?

The relationship between Tatya Patil and Sai Baba was one of profound mutual love and closeness, so much so that Tatya used to affectionately call Baba 'Mama,' or uncle. Chapter 37 illustrates that their bond was unparalleled. This unique relationship was clearly reflected in Tatya's integral role during the Chavadi procession. Baba would not begin the procession until Tatya arrived. It was Tatya Patil who would place his hand under Baba's arm to help Him rise. Furthermore, after Baba was ready, Tatya would place a beautiful golden-bordered shawl over Him and, during the walk to the Chavadi, would hold Baba's left hand, signifying his privileged and intimate role in Baba's life.
