Meditations 7.60

The body ought to be compact, and to show no irregularity either in motion or attitude. For what the mind shows in the face by maintaining in it the expression of intelligence and propriety, that ought to be required also in the whole body. But all these things should be observed without affectation.

Marcus Aurelius, Meditations 7.60, translated by George Long

The body too should be firmly set and suffer no distortion in movement or bearing. For what the mind effects in the face, by keeping it composed and well-favoured, should be looked for similarly in the whole body. But all this must be secured without conscious effort.

Marcus Aurelius, Meditations 7.60, translated by C. R. Haines
