Can you describe Sai Baba's sleeping arrangements and Mhalasapati's role in his nightly routine?

Certainly. Sai Baba had a specific routine for where he slept, alternating between two locations. As documented in Chapter 0, he would spend one night in the Masjid and the next night in the Chavadi. On the nights when Maharaj slept in the Masjid, his devotee Mhalasapati demonstrated incredible devotion by sitting with him from dusk until dawn. This routine of Mhalasapati keeping a vigil every other night continued until Mhalasapati's passing. These nights were not merely silent vigils; the text mentions that very affectionate conversations took place between them, highlighting the extremely close relationship they shared.
