Meditations 5.21

Reverence that which is best in the universe; and this is that which makes use of all things and directs all things. And in like manner also reverence that which is best in thyself; and this is of the same kind as that. For in thyself also, that which makes use of everything else is this, and thy life is directed by this.

Marcus Aurelius, Meditations 5.21, translated by George Long

Prize the most excellent thing in the Universe; and this is that which utilizes all things and controls all things. Prize in like manner the most excellent thing in thyself; and this is that which is akin to the other. For this, which utilizes all else is in thee too, and by it thy life is governed.

Marcus Aurelius, Meditations 5.21, translated by C. R. Haines
