Bhau paid more and more attention to the mast, but the more attentive he became, the more Baba rebuked him and pointed out various small mistakes that Bhau would never have thought of. Day and night he looked after Nanga Baba. The moment the mast would urinate, Bhau would clean the bed and change the sheets. The mast would never leave the bed and use the toilet, and though Bhau did his best to induce him to use the commode in his room, he was unsuccessful.
One day something incredible happened. After all the scolding he had taken on the mast's account, Bhau resolved that this day, at least, there would be no cause for Baba to be upset. Very early in the morning he cleaned and scrubbed the mast's room. He put fresh linens on the bed and kept extra bedsheets ready in case the mast spoiled the ones on his bed. Finally everything was ready, and Bhau stood outside the door waiting for Baba to come.
Baba arrived, walked into the room, and Bhau followed. As if struck by lightning, Bhau was dazed by the sight that met his eyes! A part of the wall next to the mast's bed had collapsed. Luckily, it had fallen outward, away from the mast. The amazing thing was that the wall had been in good condition, and Bhau had been standing just outside the room, and yet had heard nothing.
Very displeased, Baba asked him, "Did I give you the duty of serving Nanga Baba or killing him? Had the wall fallen inwardly, he would surely have been crushed. Have you no eyes?"
Bhau was aghast and could not reply.
"Why don't you speak?" Baba demanded. "Do you want to kill my mast? Is that why you have come here?"
Bhau finally stammered, "It is beyond my understanding. How could such a strong wall have collapsed? It was all right just moments ago."
"If your intellect does not help you, why try to use it? I say he is not mad, so why do you still use your brain and think he is? Now, tell me how the wall came down."
"I don't know. Such a solid wall could never have fallen on its own, and I didn't hear a thing. I can't understand it."
