Even if a person is flying around, if there is no ‘purpose’, it only hurts their wings.
Even if a person lives in an open world, if they do not have 'things to do,'
if they live without doing 'what they must do,' they will [end up] living while sitting still.
Even if a person lives confined in a closed space,
if they live while completing 'what they have to do,'
they will live while flying around the vast sky.
