How did Sai Baba react when a devotee criticized the way another person was massaging him?

Sai Baba's reaction to criticism of a devotee's service was swift and severe, demonstrating his acceptance of love in any form. Chapter 24 recounts an incident where a great devotee, seeing the vigorous way Baba's stomach was being pressed, became worried. He exclaimed, "Lady, have mercy! Is this any way to press the body? ... Baba's veins will break." Instead of acknowledging any pain, Baba immediately rose from his place, took his Satka (short stick) in hand, and struck the ground. His mood transformed into a "terrible rage," and his eyes, described as glowing like charcoal embers, scanned the room. This powerful, non-verbal response made it clear that he would not tolerate interference with or criticism of the loving service offered by his followers, no matter how unconventional it appeared to others.
