How did Tatya Patil's role in the Chavadi procession demonstrate his unique and close relationship with Sai Baba?

Tatya Patil's role was indispensable and highlighted his deeply personal bond with Sai Baba. As detailed in Chapter 37, even if Baba was ready to leave for the Chavadi, He would remain seated, specifically waiting for Tatya's arrival. The procession could not begin without him. Tatya would affectionately approach Baba, whom he called 'Mama' (uncle), and place a hand under His arm to help Him stand. He would then lovingly place a beautiful golden-bordered shawl over Baba. This physical closeness and Baba's insistence on waiting for him above all others showcases a mutual love and a close, familial relationship for which the text says there is no comparison.
