I remember reading some sermons by the poet, G. M. Hopkins, who was a great poet, and a Jesuit, anyway, in one sermon he kept saying that the ploughman must all the time be thinking of God, while he was ploughing. And I thought, no way, keep that damn furrow straight, that is your spiritual practice, and let go of all other thoughts. Now of course, they all have satnavs in the cab, and the tractor drives itself, lazy sods.
