How did Sai Baba manage the different devotees serving him and what was his specific role in de-escalating the argument between Anna and Mavshibai?

According to Chapter 24, Sai Baba had a unique way of managing his devotees. He would often "watch neutrally, unknowingly making devotees quarrel," and then reconcile them when their anger had passed. He allowed all devotees, men and women, to serve him physically. During Mavshibai's intense stomach massage, he seemed "completely at ease." When the argument between her and Anna grew, Baba took an active role. Out of concern for them both, he "planned a powerful trick to cool them both down." Instead of scolding them, he used humor and wisdom, lovingly asking Anna why he was upset and stating, "I don't understand what is improper in taking a kiss from the Mother." This comment reframed the situation, causing the quarrel to vanish and turning the moment into a shared joke.
