Master Lu-tsu said:
The two mistakes of indolence and distraction must be combated by quiet work that is carried on daily without interruption; then success will certainly be achieved. If one is not seated in meditation, one will often be distracted without noticing it. To become conscious of the distraction is the mechanism by which to do away with distraction. Indolence of which man is conscious, and indolence of which man is unconscious, are a thousand miles apart. Unconscious indolence is real indolence; conscious indolence is not complete indolence, because there is still some clarity in it. Distraction comes from letting the mind wander about; indolence comes from the mind’s not yet being pure. Distraction is much easier to correct than indolence. It is as in sickness: if one feels pains and irritations, one can help them with remedies, but indolence is like a disease that is attended by lack of realization. Distraction can be counteracted, confusion can be straightened out, but indolence and lethargy are heavy and dark. Distraction and confusion at least have a place, but in indolence and lethargy the anima alone is active. In distraction the animus is still present, but in indolence pure darkness rules. If one becomes sleepy during meditation, that is an effect of indolence. Only breathing serves to overcome indolence. Although the breath that flows in and out through the nose is not the true breath, the flowing in and out of the true breath takes place in connection with it.
While sitting, one must therefore always keep the heart quiet and the energy concentrated. How can the heart be made quiet? By the breath. Only the heart must be conscious of the flowing in and out of the breath; it must not be heard with the ears. If it is not heard, then the breathing is light; if light, it is pure. If it can be heard, then the breath-energy is rough; if rough, then it is troubled; if it is troubled, then indolence and lethargy develop and one wants to sleep. That is self-evident.
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; 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 harkening outward, they close themselves and are inclined to sink inward. Only when one looks and harkens 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 the moon.
If, as a result of indolence, one becomes sleepy, one should stand up and walk about. When the mind has become clear one should sit down again. In the course of time there will be success without one’s becoming indolent and falling asleep.
One hot afternoon an owl was sitting in a tree and a swan flew up and sat there too.
“Phew, it is hot, Brother Owl,” he said. “The sun is bright and I am all hot and sweaty.”
“What!” said the owl. “What? What are you talking about? Sun? Hot? When darkness gathers it gets hot. What is this sun you are talking about? Are you mad or something? What are you trying to tell me? There is no such thing as the sun. There has never been. What is this light that gets hot? We have never heard about it. It gets hot when darkness gathers. Are you trying to make a fool of me? And I’m not alone in saying so. All our scriptures also say so.”
The swan was flabbergasted with all this. “How can I explain it to this blind old owl?” he thought.
