As long as you have rules, you have a chance for freedom. To try to obtain freedom without being aware of the rules means nothing.

When we realize the everlasting truth of “everything changes” and find our composure in it, we find ourselves in Nirvana.

We say, “To hear the sound of one hand clapping.” Usually the sound of clapping is made with two hands, and we think that clapping with one hand makes no sound at all. But actually, one hand is sound. Even though you do not hear it, there is sound. If you clap with two hands, you can hear the sound. But if sound did not already exist before you clapped, you could not make the sound. Before you make it there is sound. Because there is sound, you can make it, and you can hear it. Sound is everywhere. If you just practice it, there is sound. Do not try to listen to it. If you do not listen to it, the sound is all over. Because you try to hear it, sometimes there is sound, and sometimes there is no sound. Do you understand? Even though you do not do anything, you have the quality of zazen always. But if you try to find it, if you try to see the quality, you have no quality.
