Based on the incident with Damu Anna, what can we learn about Mavshibai's personality and her method of serving Baba?

The text from Chapter 24 reveals several aspects of Mavshibai's character. We learn her original name was Venubai Kaujalgi and that Sai Baba affectionately called her "Mother" (Aai). She was a mature, widowed devotee with "incomparable devotion." Her service was intensely physical; she would twist and "grind" Baba's stomach as if churning buttermilk, causing his body to move up and down. While this method seemed strange to onlookers like Anna, the text clarifies it was an expression of "pure love" and "guileless love." Furthermore, her joking accusation towards Anna shows she had a humorous and playful side, even if it led to a temporary misunderstanding. She was clearly fearless and completely absorbed in her service.
