"If you set yourself out in Buddha's world and practice zazen, the way-seeking mind, the bodhi-mind, appears. This is mind arousing time as zazen. In the next moment you hate zazen and want to go back to sleep, so the way-seeking mind disappears. Where does it go? It disappears in timelessness. Later you want to do zazen again. That is time arousing mind as religious aspiration. So you sit down and come back to practicing zazen. Then the way-seeking mind comes up again. All you have to do is continue arousing the way-seeking mind. If you practice like this, this is arousing time as zazen. So do zazen as whole-hearted practice and become completely one with time as zazen. Then time takes care of your life.
The way-seeking mind is not something you try to get. You just set yourself out in Buddha's world and do zazen whole-heartedly. When the time is ripe and conditions are arranged, the way-seeking mind comes up in your life, blooms, and is the rhythm of the whole world. Then time is called zazen and zazen is the whole world of time.
The whole world comes together into your zazen, but it doesn't bother your zazen. The sound of a car doesn't bother you, the sound becomes one with zazen. People sitting next to you don't bother you. Zazen doesn't bother you, and your zazen doesn't bother others. You just sit, blooming your life. This is called satori, enlightenment" - Each Moment is the Universe, Katagiri Roshi.
