When there is teaching, you must follow the line free from expectation and anticipation — as in the same way when you trace the route on the map it brings you to your destination. It is very deeply rooted in the body- mind that there is something to achieve, to become, to attain, and this brings us absolutely away from what we are. It takes us in the opposite direction. So we must first face our body- mind, accept it, explore it, get to know it. In this exploration there comes a moment when you are no longer interested in what you explore but live in the exploring itself. The explored is in the exploring, but the exploring is not in the explored. In other words, the known is in the knowing, but the knowing is not in the known. Otherwise, there could not be knowing.
By “explore the body-mind” I mean sense the body-mind. And by “sense” I 
mean have the sensation of it. Systematically go through all the parts and let each part become sensitive. In this way you become aware of your body. The body is only known through the five senses so let it come up to your five senses. The most obvious of all the sense faculties is sensation or feeling. We know our bodies mostly through sensation. In sensing the body you become free from the reactive body, free from mechanical functioning. So the moment you explore, sense, your body you no longer feed its conditioning. There’s no longer an accomplice to it, to its tension, expectation, aggression. There’s a letting-go, a deep relaxation. Then there’s a moment when there’s no more emphasis on the object, the body-mind, and there’s a switchover so that the observer-subject-explorer is emphasized. You find yourself objectless, no longer in relation of subject to object— abiding completely in stillness, in beingness. That is self-knowing.
Become free from undertaking, from doing. Not doing is also an undertaking. Doing and not doing are movements in the mind. And the mind, like all objects, has its roots in the self, in our highest principle. It is only in this higher principle that there is a conversion between doing and not doing. In this conversion there is no more left and right, yes and no, like and dislike, doing and not-doing; you are free from duality, there is really wholeness, completeness. It no longer has anything to do with the mind.
