Enchiridion 39

Each man's body is a measure for his property, just as the foot is a measure for his shoe. If, then, you abide by this principle, you will maintain the proper measure, but if you go beyond it, you cannot help but fall headlong over a precipice, as it were, in the end. So also in the case of your shoe; if once you go beyond the foot, you get first a gilded shoe, then a purple one, then an embroidered one. For once you go beyond the measure there is no limit.

Epictetus, Enchiridion 39, translated by W. A. Oldfather

The measure of possession (property) is to every man the body, as the foot is of the shoe. If then you stand on this rule (the demands of the body), you will maintain the measure: but if you pass beyond it, you must then of necessity be hurried as it were down a precipice. As also in the matter of the shoe, if you go beyond the (necessities of the) foot, the shoe is gilded, then of a purple colour, then embroidered: for there is no limit to that which has once passed the true measure.

Epictetus, Enchiridion 39, translated by George Long

Every man's body is a measure for his property, as the foot is the measure for his shoe. If you stick to this limit, you will keep the right measure; if you go beyond it, you are bound to be carried away down a precipice in the end; just as with the shoe, if you once go beyond the foot, your shoe puts on gilding, and soon purple and embroidery. For when once you go beyond the measure there is no limit.

Epictetus, Enchiridion 39, translated by P. E. Matheson
