Once upon a time Laisrén went presumptuously 1 from the monastery of Clúain in order to purify Clúain Cháin, a church which is in the territory of Connaught. He fasted thrice three days while purifying the church. At the end of the third three days' fast sleep overpowered him in the oratory, and in his sleep he heard a voice saying to him: ‘Arise!’ The first time he did not move. When for the second time he heard the voice he raised his head and made the sign of the cross over his face. Then he saw the church in which he was, all alight, and yet there was still a part of the night. And between the chancel and the altar he saw a shining figure.
