400+ Sourced quotes
The Stoics say, "Retire within yourselves; it is there you will find your rest." And that is not true. Others say, "Go out of yourselves; seek happiness in amusement." And this is not true. Illness comes. Happiness is neither without us nor within us. It is in God, both without us and within us.
The love, more especially, which is concerned with the good, and which is perfected in company with temperance and justice, whether among gods or men, has the greatest power, and is the source of all our happiness and harmony, and makes us friends with the gods who are above us, and with one another.
