What does the text reveal about the special relationship between Sai Baba and Tatya Patil regarding the Chavadi procession?

The text from Chapter 37 highlights a uniquely deep and affectionate relationship between Sai Baba and Tatya Patil. It reveals that Baba would not start the procession, even if He was otherwise ready, until Tatya arrived. The departure from the Masjid was initiated only when Tatya Patil physically put his hand under Baba's arm and helped Him to stand. This act demonstrates a profound interdependence and trust. The narrative further emphasizes their bond by noting that Tatya affectionately called Baba 'Mama' (uncle) and that there was "no comparison to give for their close relationship."
