What was the relationship between Sai Baba and Tatya Patil like, based on the description of the Chavadi procession?

The bond between Sai Baba and Tatya Patil was exceptionally close and filled with mutual love. Chapter 37 highlights this by noting there is "no comparison to give for their close relationship." Tatya affectionately called Baba 'Mama,' which means maternal uncle. His importance is shown by the fact that Baba would not begin the procession to the Chavadi until Tatya arrived. Tatya would then initiate the departure by placing his hand under Baba's arm to help Him stand. He would also personally place a beautiful golden-bordered shawl over Baba, demonstrating a deep, personal, and loving connection that was integral to this ceremony.
