Meditation 8.35
Marcus AureliusMeditationsBook 8.35
35. As each reasonable creature receives the rest of his abilities from the Nature of the Whole, so have we received this ability, too, from her.[3] Just as she converts every obstacle and resistance, puts it into its place in the order of necessity and makes it a part of herself, so, too, the reasonable creature can make every obstacle material for himself and employ it for whatever kind of purpose he has set out upon.
