Describe the devotee Mavshibai and her unique method of serving Sai Baba.

Mavshibai, whose original name was Venubai Kaujalgi, was a devoted, mature-aged widow whom Sai Baba affectionately called "Mother" (Aai). Chapter 24 highlights her incomparable devotion to Sai's feet. Her service involved physically massaging Baba, but her method was particularly extraordinary and energetic. The text describes her as twisting with both hands and "grinding" Baba's stomach as if churning a pot of buttermilk. This vigorous pressing, born of pure love and absorption in Sai's name, would make Baba's stomach and back flat and cause his whole body to move up and down. Despite the apparent force, Baba remained completely at ease, accepting this unique and guileless form of service.
