Could you explain the special bond and routine between Sai Baba and Tatya Patil before the Chavadi procession?

Chapter 37 details the profound love between Sai Baba and Tatya Patil, who affectionately called Baba 'Mama'. Their connection was so deep that even if Baba was ready for the Chavadi procession, He would not move from His spot until Tatya arrived. The text explicitly states that only when Tatya Patil came and physically put his hand under Baba's arm to raise Him would Baba prepare to leave the Masjid. This routine, along with Tatya placing a beautiful golden-bordered shawl over Baba, highlights their unique and incomparable relationship.
