Book VIII · 27
There are three relations [between thee and other things]: the one to the body3 which surrounds thee; the second to the divine cause from which all things come to all; and the third to those who live with thee.
Thou hast three relationships—the first to the vessel thou art contained in; the second to the divine Cause wherefrom issue all things to all; and the third to those that dwell with thee.
Marcus Aurelius, Meditations VIII.27. Translated by George Long (1862). The Stoic Library.
