“On the way back, Columba made a little detour. From a mound above the monastery he blessed it and all the people who would in the future come to the island [Iona] for his sake. Then he returned to his cell, not to rest but to go on with his daily stint of copying the scriptures. He was working on the thirty-fourth psalm. He wrote steadily for a while, but when he got to the verse that says, They that seek the Lord shall not want any good thing, he put down his pen. It seemed a perfect place to stop.
"I think I can write no more," he said.”
