Walking is Zen; sitting, too.
Let Your Mind Go
The most important thing is to stay nimble, stay with things they are, and keep awake. There’s going on retreat and there’s returning home or as they call it in the Zen tradition, “returning to the marketplace.” There’s clarity in solitude, and there’s clarity as you drive your car on Route 95 during rush hour.
Even the slightest hint of holiness or righteousness will take you away from just doing it. Keen-eyed people can see it coming from miles away and they’ll run for their lives. Who can blame them? If you have a Zen idea, it’s still that: an idea. Let your mind go any place without hindrance.
