Can you explain Sai Baba's regular routine concerning the Masjid and the Chavadi?

According to the details provided in Chapter 51, Sai Baba followed a strict and constant rule regarding his place of rest, which continued uninterrupted throughout His life. This routine involved alternating His nights between two locations in Shirdi. He would spend one night sleeping in the Masjid, and the following night He would stay in the Chavadi. The journey from the Masjid to the Chavadi on its designated evening evolved into the celebrated Chavadi procession, a significant event for all His devotees.
