Can you describe the close relationship between Mhalasapati and Sai Baba?

Mhalasapati and Sai Baba shared an exceptionally close and affectionate relationship. According to Chapter 0, Sai Baba would alternate sleeping between the Masjid and the Chavadi. On the nights Maharaj slept in the Masjid, Mhalasapati would faithfully sit by his side until dawn. During these nights, the two engaged in very affectionate conversations. This routine was a testament to Mhalasapati's unwavering devotion, as he continued this practice of staying up all night every other day until he passed away. He was considered highly advanced and a source of guidance for other devotees.
