Can you describe Mavshibai's particular method of serving Baba and how other devotees reacted to it?

Mavshibai, whose original name was Venubai Kaujalgi, had a very distinct and vigorous way of serving Sai Baba. Chapter 24 explains that while massaging Baba's stomach, she would twist and churn with both hands "like a pot of buttermilk," with a force that made his stomach and back appear flat. This was an expression of her pure love and devotion, and Baba seemed completely at ease with it. However, her method elicited different reactions from others. Damu Anna felt pity watching her. In another instance mentioned in Chapter 24, a different great devotee became worried and exclaimed that she should have mercy, fearing Baba's veins would break. This criticism angered Baba, who immediately rose and struck the ground with his Satka in a terrible rage.
