The situation in the citation

Four Zen students, and close friends, promised each other to keep silence in order to deepen their meditation. The first day was silent. Their meditation began favorably, but when the night came and the petroleum lamps became very dull, one of the disciples could not hold back and shouted to the servant:
Repair these lamps.
The second disciple was surprised when he heard the first spoke.
We agreed not to say a word, he said.
You, Bollywood, what are you talking about? I asked the third.
I am silent, the fourth.
