Walking meditation is also called Kinhin and is associated with Theravada and Mahayana Buddhism which involves movement between long periods of sitting meditations. Walking meditations commonly follow Zazen meditations.
You do walking meditation by first making a fist with your right hand with the thumb on the inside. This is a sign of non-violence. Then you wrap your left hand around your right fist and with your head bowed slightly you take slow, managed steps. Although others have been known to use quick strides.
When you take steps you place your foot out in front of you and you do not move your other foot until the first foot has made full contact with the floor. Then, you do not start to lift the foot for the next step until the full weight of your body is shifted to the other side. A full breath is taken between each step.
You continue making the slow strides while maintaining the meditative state from your Zazen Meditation. Sometimes chanting is done at the same time. It is a quick nice meditation you can use while you are out and about to bring quick calm to yourself.
Like normal walking and jogging walking meditation is good for your health by reducing cortisol in your blood and improving your overall mood.
