1. Sit on the forward third of a chair or a cushion on the floor.
2. Straighten and extend your spine, keeping it naturally upright, centering your balance in the lower abdomen. Push your lower back a little forward, open your chest, and tuck your chin in slightly, keeping the head upright, not leaning forward, or backwards, or to the side. Sway your body gently from left to right in decreasing arcs, until you naturally come to a point of stillness on your cushion.
3. Keep your eyes on the floor at a 45-degree angle, neither fully opened nor closed, and gaze naturally about 3 to 4 feet in front of your body. If the eyes are closed, you may want to start to daydream or visualize things. If your eyes are open wide open, your mind will scatter.
4. Keep your lips and teeth together with your tongue resting against the roof of your mouth.
5. Place your hands on your lap with the right palm up and your left hand (palm up) resting on your right hand, thumb tips lightly touching, forming a vertical oval. This is the mudra of zazen, in which all phenomena are unified. Rest this mudra with the blade of your hands against your abdomen, a few inches below the navel, harmonizing your own center of gravity with the mudra.
6. Take a deep breath, exhale fully, and then take another deep breath, exhaling fully. Let your breathe settle into its natural rhythm.
7. Keep your attention on your breath. When your attention wanders, bring it back to the breath again and again — as many times as necessary!
8.. Practice this Zen Meditation every day for at least ten to fifteen minutes (or longer).
