When you are to relax, simply sit down, or lie down, nothing in your mind, not doing this for the sake of something, not doing this to know something, not doing this to become enlightened, be in calmness with empty mind.
When you get up for action, you simply move, nothing in your mind, and simply clear up the things that need to be done.
There is no need for temples, for monks, for gurus, for scriptures. Zen sitting is not for gaining enlightenment. Zen sitting is not for solving your mental pains and problems. It is simply being in calmness, relaxing in the sake of nothing.
Only to recognize that all that was needed, was simply THAT, and until you recognize that the only precious thing was THAT, searching and looking for something that looks unusual and outstanding, trying out and doing everything exhaustively that seems necessary to be done, until you understand that all was really unnecessary to be done, are all the purposes of training.
If you wish to open yourself to enlightenment, you should begin by "loving" the quietness of empty mind, "loving" the inactions and actions with nothing in your mind. There is a well-said idiom, "Love comes around while doing things you like." How could you relax in empty mind, without at first, "loving" the nothingness of your mind?
How could you get along well with the empty mind, not "at first felling in love" with it? If trainings, spiritual works, Zen sittings, active Zen workouts, and all the other practices were hard, difficult and painful task to do, how could you get on well with the empty mind?
Sit or move, with nothing in your mind, searching for, hoping for, expecting for nothing, just simply get your mind off from the wandering mind or the enlightened mind, and give your body and soul over to the nothingness of your mind, knowledgeless and powerless nothingness.
The true man with no rank, the original face, the true self, the true nature, Buddha-Dhatu, the supreme subject, those are the different names of something residing inside you, which is since ancient times in India, so-called the observer at the center.
Therefore, anything that was perceived would mean that it is not THAT. Whether gained from Zen sitting or meditation, any experience and perception is absolutely not THAT. Even the perception being sensed here right now, truly as it is, is not THAT.
Furthermore, being aware of the feeling of self existence here, right now, is not THAT.
If you wish to embody THAT, sit down calmly not minding the posture, and after you close your eyes contemplating your surroundings as darkness of absolute nothingness, then dissolve and erase everything inside your body and your brain into darkness.
At the moment, do not try to see anything even though your eyes are open, and let the eyes float freely. Walk with your sight vague, never gazing strongly upon something. Try to slow down your blinks, and the movement of your sight.
