A brother came to Poemen in the second week of Lent and told him his thoughts, and found peace of mind from his answer. Then he said, ‘I almost didn’t come to see you today.’ Poemen asked him why. He said, ‘I was afraid that the door wouldn’t be opened as it is Lent.’ Poemen answered him, ‘It is not wooden doors we were taught to shut; the door we need to keep shut is the mouth.’
