The text mentions Baba and Tatya Patil's close bond, but was it truly special or was Tatya's role just to help an old man get up so the ceremony could start?

The relationship between Sai Baba and Tatya Patil was portrayed as being exceptionally deep and based on mutual love, not merely functional. Chapter 37 explicitly states there is "no comparison to give for their close relationship." This is demonstrated by the fact that even if Baba was ready, He would intentionally remain seated and wait for Tatya Patil to arrive. The procession would not commence until Tatya came and put his hand under Baba's arm to help Him stand. The detail that Tatya affectionately called Baba 'Mama' (uncle) further underscores the personal, familial nature of their bond, which clearly transcended a simple ceremonial duty.
