How easy it is to repel and release every impression which is troublesome and immediately to be tranquil.

The best way of avenging thyself is not to become like the wrong-doer.

Whoever values peace of mind and the health of the soul will live the best of all possible lives.

For nowhere either with more quiet or more freedom from trouble does a man retire than into his own soul, particularly when he has within him such thoughts that by looking into them he is immediately in perfect tranquility; and I affirm that tranquility is nothing else than the good ordering of the mind.
