Walking is a wonderful way of meditating. It brings one to the point of realising that meditation does not depend upon the position of the body. Sitting, standing, lying down, walking — what is the difference when one is aware? The state of being aware is an experience which goes beyond the body.
The formal practice of walking is very useful in retreat situations where a lot of sitting is taking place and the body gets stiff. To walk for ten minutes or so between periods of sitting, stretches the joints and can bring relief to aching knees, ankles and so on. But more than that, in a sense, walking meditation is like putting sitting meditation into motion. This can break down any misconceptions about meditation being something only to take place in perfect stillness.
Freedom from form, feeling, mental activity, perception and consciousness — this little bundle called ‘me’ — can be experienced at any time just by engaging in the business at hand in a meditative way, whether it be the rise and fall of the abdomen, or the placing of one foot in front of the other in walking meditation.
