“Leisure is not the attitude of mind of those who actively intervene, but of those who are open to everything; not of those who grab and grab hold, but of those who leave the reins loose and who are free and easy themselves–almost like a man falling asleep, for one can only fall asleep by ‘letting oneself go.’ Sleeplessness and the incapacity for leisure are really related to one another in a special sense, and a man at leisure is not unlike a man asleep. Heraclitus the Obscure observed of men who were asleep that they too ‘were busy and active in the happenings of the world.’ When we really let our minds rest contemplatively on a rose in bud, on a child at play, on a divine mystery, we are rested and quickened as though by a dreamless sleep.”
