Could you describe the unique way Mavshibai performed service for Sai Baba?

Mavshibai, whose real name was Venubai Kaujalgi, had a very physical and intense method of serving Baba. Chapter 24 details how she would press Baba's stomach and side with such force that her breath became uncontrollable. Absorbed in Sai's name, she would twist with both hands, "grinding" his stomach and churning it "like a pot of buttermilk." This extraordinary way of pressing was so vigorous it made Baba's body move up and down. While it elicited pity in Damu Anna's heart, the text clarifies it was an expression of pure, guileless love, a service Baba accepted with complete ease.
