Can you describe Mavshibai's unique way of serving Sai Baba and how other devotees reacted to it?

Mavshibai, whose original name was Venubai Kaujalgi, served Sai Baba with a particularly intense form of massage. Chapter 24 details how she would press and churn Baba's stomach "like a pot of buttermilk," with such force that her breath became uncontrollable. Despite the apparent roughness, which made Baba's stomach and back look flat, it was an act of pure love, and Baba himself seemed completely at ease. However, other devotees had different reactions. Damu Anna felt pity watching her. In a separate incident mentioned in the same chapter, another devotee became worried and told her to be more gentle, fearing she would injure Baba, which in turn angered Baba himself for the interference in her loving service.
