Can you describe how Mavshibai used to serve Sai Baba? It sounds like her massaging was very intense.

Yes, Mavshibai's method of serving Sai Baba was indeed very intense and unique. Chapter 24 describes her service in detail. While pressing Baba's stomach and side, she would become so absorbed that her breath became uncontrollable. The text states she would twist with both hands and begin "grinding" his stomach, pressing and churning it like a pot of buttermilk. Her extraordinary way of pressing was so forceful that it made Baba's stomach and back appear flat, and it caused him to move up and down. Despite the intensity, which made Damu Anna feel pity, Baba seemed completely at ease and never complained. This was seen as an expression of her pure, guileless love and devotion to him.
