Excerpt from "Noticing Space," by
To examine the thinking process, deliberately think something: take just one ordinary thought, such as “I am a human being,” and just look at it. If you look at the beginning of it, you can see that just before you say “I,” there is a kind of empty space. Then, if you think in your mind, “I—am—a—human—being,” you will see space between the words. We are not looking at thought to see whether we have intelligent thoughts or stupid ones. Instead, we are deliberately thinking in order to notice the space around each thought. This way, we begin to have a perspective on the impermanent nature of thinking.
That is just one way of investigating so that we can notice the emptiness when there is no thought in the mind. Try to focus on that space; see if you can concentrate on that space before and after a thought. For how long can you do it? Think, “I am a human being,” and just before you start thinking it, stay in that space just before you say it. Now that’s mindfulness, isn’t it? Your mind is empty, but there is also an intention to think a particular thought. Then think it, and at the end of the thought, try to stay in the space at the end. Does your mind stay empty?
Most of our suffering comes from habitual thinking. If we try to stop it out of aversion to thinking, we can’t; we just go on and on and on. So the important thing is not to get rid of thought, but to understand it. And we do this by concentrating on the space in the mind, rather than on the thought.
Our minds tend to get caught up with thoughts of attraction or aversion to objects, but the space around those thoughts is not attractive or repulsive. The space around an attractive thought and a repulsive thought is not different, is it? Concentrating on the space between thoughts, we become less caught up in our preferences concerning the thoughts. So if you find that an obsessive thought of guilt, self-pity, or passion keeps coming up, then work with it in this way—deliberately think it, really bring it up as a conscious state, and notice the space around it.
It’s like looking at the space in a room: you don’t go looking for the space, do you? You are simply open to it, because it is here all the time. It is not anything you are going to find in the cupboard or in the next room, or under the floor—it is here right now. So you open to its presence; you begin to notice that it is here.
