How to use the heart correctly during breathing must be understood. It is a use without use. One should only let the light fall quite gently on the hearing. This sentence contains a secret meaning. What does it mean to let the light fall? It is the spontaneous radiation of the light of the eyes. The eye looks inward only and not outward. To sense brightness without looking outward means to look inward. To sense brightness without looking outward means to look inward; it has nothing to do with an actual looking within. What does hearing mean? It is the spontaneous hearing of the light of the ear. The ear listens inwardly only and does not listen to what is outside. To sense brightness without listening to what is outside is to listen inwardly; it has nothing to do with actually listening to what is within. In this sort of hearing, one hears only that there is no sound; in this kind of seeing, one sees only that no shape is there. If the eye is not looking outward and the ear is not hearkening outward, they close themselves and are inclined to sink inward. Only when one looks and hearkens inward does the organ not go outward nor sink inward. In this way indolence and lethargy are done away with. That is the union of the seed and the light of the sun and moon.
