On a good walk, the mind is not completely blank. It can’t be—otherwise you might trip over a root or get hit by a car or a bicyclist. The point is not, as in traditional meditation, to push every thought or observation from your mind. On the contrary, the whole point is to see what’s around you. The mind might be active while you do this, but it is still. It’s a different kind of thinking, a healthier kind if you do it right.
