Could you describe Mavshibai's unique way of serving Sai Baba and how others perceived it?

Mavshibai, whose original name was Venubai Kaujalgi, was a devoted widow whom Baba affectionately called "Mother" (Aai). Her method of service, described in Chapter 24, was extraordinarily intense. When massaging Baba's stomach and sides, she would twist and churn with both hands as if grinding a pot of buttermilk. She was so absorbed in her service that she pressed fearlessly, making Baba's stomach and back appear flat. While her service was an act of pure love and Baba seemed completely at ease, it appeared strange and even alarming to others. For instance, Damu Anna felt pity watching her, and another unnamed devotee expressed worry that her vigorous pressing would break Baba's veins. This shows that her service was perceived as excessive by some, even though it stemmed from incomparable devotion.
