Can you describe the special relationship between Sai Baba and Tatya Patil as depicted during the Chavadi procession?

Chapter 37 reveals the deeply affectionate and essential relationship between Sai Baba and Tatya Patil. Their bond was so close that Tatya would call Baba 'Mama' (uncle), a term indicative of their mutual love, which the text describes as beyond comparison. Tatya's role in the Chavadi procession was indispensable. Sai Baba would patiently wait for Tatya's arrival before starting, and would only prepare to stand and leave once Tatya Patil placed a hand under His arm to assist Him. Furthermore, Tatya would lovingly place a beautiful golden-bordered shawl over Baba, adjusting it properly on His head, showcasing a relationship built on deep reverence and intimate care.
