It has been said that the highest wisdom lies in detachment, or, in the words of Chung-Tzu, ‘The perfect man employs his mind as a mirror; it grasps nothing; it refuses nothing; it receives, but does not keep.’ Detachment means to have neither regrets for the past nor fears for the future; to let life take its course without attempting to interfere with its movement and change, neither trying to prolong the stay of something pleasant nor to hasten the departure of things unpleasant. To do this is to move in time with life, to be in perfect accord with its changing music, and this is called Enlightenment.
In short, it is to be detached from both the past and future and to live in the eternal Now. For in truth neither past nor future have any existence apart from this Now; by themselves they are illusions. Life exists only at this very moment, and in this moment it is infinite and eternal. For the present moment is infinitely small; before we can measure it, it has gone, and yet it persists forever.
,,,A sage has said that if we try to accord with it, we shall get away from it. But he was not altogether right. For the curious thing is that you cannot get out of accord with it even if you want to; though your thoughts may run into the past or the future they cannot escape the present moment. However far back or forward they try to escape they can never be separated from the moment, for those thoughts are themselves of the moment; just as much as anything else they partake of, and, indeed, are the movement of life which is Tao.
You may believe yourself out of harmony with life and its eternal Now; but you cannot be, for you are life and exist Now—otherwise you would not be here. Hence the infinite Tao is something which you can neither escape by flight nor catch by pursuit; there is no coming toward it or going away from it; it is, and you are it. So become what you are.
