Often we read or hear that we should stop the activity of thinking in order to meditate properly. But that is almost impossible. The mechanism of thinking is going on constantly like a rushing torrent, and although you can stop it for a few moments, it always wins. It’s like the bubbles in a fish tank. When we sit, we think the thought of zazen. When we breath, we think the thought of breathing, when sitting up straight, we think the thought of balance, and when working, we think the thought of work. In other words, our thought and our activity become one. Thinking and that which is thought are not separate.
Master Dogen calls this (“Think not thinking”) the art of zazen. When there is no gap, there is no discrimination. When our thoughts wander, as they will because they are always hungry, we bring them home where they belong, and include them in some satisfying work. When our thoughts sit zazen, they become enlightened. So when you sit, think the thought of zazen.
