The peace of mind on offer here is of a higher order: it lies in the recognition that being unable to escape from the problems of finitude is not, in itself, a problem. The human disease is often painful, but as the Zen teacher Charlotte Joko Beck puts it, it’s only unbearable for as long as you’re under the impression that there might be a cure. Accept the inevitability of the affliction, and freedom ensues: you can get on with living at last.
