How did the styles of service performed by Anna and Mavshibai differ in the scene described?

The chapter highlights a stark contrast in the styles of service rendered by the two devotees. According to Chapter 24, Anna's service was gentle and steady. He was positioned leaning over a railing, slowly pressing Sai Baba's left hand. In contrast, Mavshibai's service was extraordinarily vigorous and dynamic. She was twisting and "grinding" Baba's stomach with both hands, churning with such force that it was compared to churning a pot of buttermilk. Her movements were so energetic that Baba's body moved up and down with her rhythm. This shows that Baba accepted all forms of devoted service, from the gentle pressing by Anna to the fearless and powerful massaging by Mavshibai.
