Repetition
If an artist becomes too idealistic, he will commit suicide, because between his ideal and his actual ability there is a great gap. Because there is no bridge long enough to go across the gap, he will begin to despair. That is the usual spiritual way. But our spiritual way is not so idealistic. In some sense we should be idealistic; at least we should be interested in making bread which tastes and looks good! Actual practice is repeating over and over again until you find out how to become bread. There is no secret in our way. Just to practice zazen and put ourselves into the oven is our way.
