The passing minute is every man's equal possession but what has once gone by is not ours.
Marcus AureliusRemember that the sole life which a man can lose is that which he is living at the moment.
Marcus AureliusConstantly regard the universe as one living being, having one substance and one soul; and observe how all things have reference to one perception, the perception of this one living being; and how all things act with one movement; and how all things are the cooperating causes of all things which exist; observe too the continuous spinning of the thread and the contexture of the web.
Marcus AureliusFor 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.
Marcus Aurelius
