What was Tatya Patil's specific role in the Chavadi procession, and what does it reveal about his relationship with Sai Baba?

Tatya Patil played an indispensable role in initiating the Chavadi procession. Chapter 37 explains that even when everything was ready, Sai Baba would not leave the Masjid until Tatya Patil arrived. Baba would wait for him specifically. It was only when Tatya came and put his hand under Baba's arm to help Him up that Baba would prepare to leave. This act highlights their incredibly close and loving relationship, which the author notes is beyond comparison. Tatya affectionately called Baba 'Mama' (uncle), and he would also place a beautiful golden-bordered shawl over Baba before they departed, signifying their deep mutual affection.
