Can you describe the contrasting styles of service performed by Damodar Anna and Mavshibai right before their argument?

The source material in Chapter 24 provides a vivid contrast between the two devotees' methods of service. Damodar Anna, an elderly man described as having no teeth, was performing a gentle service. He was 'leaning forward from outside, slowly pressing the left hand' of Sai Baba. In stark contrast, Mavshibai, also of mature age, was serving with fearless and intense physical energy. She was 'twisting with both hands' and 'grinding' Baba's stomach, pressing and churning 'like a pot of buttermilk.' Her extraordinary method, born of pure love, was so vigorous that it made Baba's stomach and back flat, a strange form of service that initially looked jarring to Anna.
