Be careful that you're not turned into a Caesar, dyed with that dye. It happens.
Keep yourself simple, good, pure, serious, and free of affectation: a friend of justice, a worshipper of the gods, kind, affectionate, and energetic in every proper action.
Strive to remain what philosophy wished to make you.
Revere the gods and help people.
Life is short. This earthly life has one harvest: a devout disposition and actions for the common good.
Do everything as a disciple of Antoninus.
Remember his constancy in every rational act, his evenness, his piety, the serenity of his expression, his gentleness, his disregard for empty fame, and his effort to understand things thoroughly.
He never let anything pass without examining it carefully and understanding it clearly.
He bore unjust blame without blaming in return.
He did nothing in a hurry, refused to listen to slander, and examined character and conduct closely.
He was not fault-finding, timid, suspicious, or fond of quibbling.
Little contented him in lodging, bed, clothing, food, and servants.
He was hard-working and patient. His spare diet let him continue until evening without needing to relieve himself earlier.
He was steady and constant in friendship.
He tolerated people who spoke freely against his opinions and was pleased when someone showed him a better way.
He was religious without superstition.
Imitate all this, so that when your last hour comes you may have as good a conscience as he had.
