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.
Marcus AureliusKeep in mind how fast things pass by and are gone - those that are now, and those to come. Existence flows past us like a river; the "what" is in constant flux, the "why" has a thousand variations. Nothing is stable, not even what's right here. The infinity of past and future gapes before us - a chasm whose depths we cannot see.
Marcus Aurelius
