What was the relationship between Sai Baba and Tatya Patil, especially in the context of the Chavadi procession?

The relationship between Sai Baba and Tatya Patil was one of profound mutual love and closeness, as highlighted in Chapter 37. Tatya affectionately called Baba 'Mama' (uncle), and their bond was considered unparalleled. In the context of the Chavadi procession, Tatya's role was indispensable. Baba would always wait for Tatya's arrival before leaving the Masjid. It was only when Tatya Patil placed his hand under Baba's arm to help Him up that Baba would prepare to leave. Tatya also lovingly placed a golden-bordered shawl over Baba and held His left hand during the procession, signifying his unique and intimate role.
