Only one who is 100 percent in doing can recognize the happening.
The healthiest way to apply this knowledge is to see the whole past as happening and the present as doing. If you see the past as doing, then ego and regret come along. And when you see the present as happening, then laziness and unawareness set in. If you apply the doing for the future, it brings tension and worry. If you apply the happening for the future, it might bring some confidence and also lethargy.
