Leisure stands in a perpendicular position with respect to the working process — in just the same way as the "simple gaze" of intellectus does not consist in the "duration" (so to speak) of ratio's working-out process, but instead cuts through it at the perpendicular (the ancients compared the ratio with time, the intellectus with the "always now" of eternity).
