When you do that, you have let go of your meditation and are no longer a viewer but have become a participant. Another example is the sense of smell. Now concerning the sense of touch, when you just receive the sensation that is there, this is relaxed, but when you try to feel something, this is tense. So the way to use the senses is to just receive what comes in. But now about thought and the desires.
Thought is a tool for thinking and planning.
So the way to use it is so that when you think or plan, you do it here. When you think or when you plan for later or for the future, that's all right. But when you go or reach out into the future while you are making plans for it, this is what is not right. Since your body is here, your thoughts should be here too. You should prepare, plan and think here and now, even when it is for the future.
