You are asked — temporarily, of course — to lay aside all your philosophical, religious, and political opinions, and to become almost like an infant, knowing nothing. Nothing, that is, except what you actually hear, see, feel, and smell. Take it that you are not going anywhere but here, and that there never was, is, or will be any other time than now. Simply be aware of what actually is without giving it names and without judging it, for you are now feeling out reality itself instead of ideas and opinions about it. There is no point in trying to suppress the babble of words and ideas that goes on in most adult brains, so if it won't stop, let it go on as it will, and listen to it as if it were the sound of traffic or the clucking of hens.
Let your ears hear whatever they want to hear; let your eyes see whatever they want to see; let your mind think whatever it wants to think; let your lungs breathe in their own rhythm. Do not expect any special result, for in this wordless and idea-less state, where can there be past or future, and where any notion of purpose? Stop, look, and listen...
