What was Tatya Patil's special relationship with Baba, especially concerning the start of the procession?

The bond between Tatya Patil and Sai Baba was exceptionally close, as highlighted in Chapter 37. The text emphasizes their mutual love, noting that Tatya called Baba 'Mama' (uncle). This closeness was integral to the Chavadi procession. Even if Baba was fully ready to go, He would not move from His spot. He would deliberately wait for Tatya Patil to arrive. The procession would only commence once Tatya came and put his hand under Baba's arm to raise Him, signaling the moment of departure.
