Meditation 7.28-29
Marcus AureliusMeditationsBook 7.28
28. Withdraw into yourself: the reasonable governing self is by its nature content with its own just actions and the tranquillity it thus secures.
29. Wipe away the impress of imagination. Stay the impulse which is drawing you. Define the time which is present. Recognize what is happening to yourself or another. Divide and separate the event into its causal and material aspects. Dwell in thought upon your last hour. Leave the wrong done by another where the wrong arose.
