Zen Mind, Beginner's Mind - Shunryu Suzuki [41]
So we say true understanding will come out of emptiness. When you study Buddhism, you should have a general house cleaning of your mind. You must take everything out of your room and clean it thoroughly. If it is necessary, you may bring everything back in again. You may want many things, so one by one you can bring them back. But if they are not necessary, there is no need to keep them.
We see the flying bird. Sometimes we see the trace of it. Actually we cannot see the trace of a flying bird, but sometimes we feel as if we could. This is also good. If it is necessary, you should bring back in the things you took from your room. But before you put something in your room, it is necessary for you to take out something. If you do not, your room will become crowded with old, useless junk.
We say, "Step by step I stop the sound of the murmuring brook." When you walk along the brook you will hear the water running. The sound is continuous, but you must be able to stop it if you want to stop it. This is freedom; this is renunciation. One after another you will have various thoughts in your mind, but if you want to stop your thinking you can. So when you are able to stop the sound of the murmuring brook, you will appreciate the feeling of your work. But as long as you have some fixed idea or are caught by some habitual way of doing things, you cannot appreciate things in their true sense.
If you seek for freedom, you cannot find it. Absolute freedom itself is necessary before you can acquire absolute freedom. That is our practice. Our way is not always to go in one direction. Sometimes we go east; sometimes we go west. To go one mile to the west means to go back one mile to the east. Usually if you go one mile to the east it is the opposite of going one mile to the west. But if it is possible to go one mile to the east, that means it is possible to go one mile to the west. This is freedom. Without this freedom you cannot be concentrated on what you do. You may think you are concentrated on something, but before you obtain this freedom, you will have some uneasiness in what you are doing. Because you are bound by some idea of going east or west, your activity is in dichotomy or duality. As long as you are caught by duality you cannot attain absolute freedom, and you cannot concentrate.
Concentration is not to try hard to watch something. In zazen if you try to look at one spot you will be tired in about five minutes. This is not concentration. Concentration means freedom. So your effort should be directed at nothing. You should be concentrated on nothing. In zazen practice we say your mind should be concentrated on your breathing, but the way to keep your mind on your breathing is to forget all about yourself and just to sit and feel your breathing. If you are concentrated on your breathing you will forget yourself, and if you forget yourself you will be concentrated on your breathing. I do not know which is first. So actually there is no need to try too hard to be concentrated on your breathing. Just do as much as you can. If you continue this practice, eventually you will experience the true existence which comes from emptiness.
In the Prajna Paramita Sutra the most important point, of course, is the idea of emptiness. Before we understand the idea of emptiness, everything seems to exist substantially. But after we realize the emptiness of things, everything becomes real-not substantial. When we realize that everything we see is a part of emptiness, we can have no attachment to any existence; we realize that everything is just a tentative form and color. Thus we realize the true meaning of each tentative existence. When we first hear that everything is a tentative
