You cannot measure good by either the feeling of need or sacrifice, but only by the communication with God which is established between the giver and the receiver.
Life alone is not good. Goodness exists only in a proper, virtuous life.
— Lucius Annaeus Seneca
It is not a virtue, but a kind of deceitful similitude, to fulfill our duty for the purpose of its reward.
— Marcius Tullius Cicero
All people become closer, more or less, to one of two opposite limits: one is life only for oneself, and the other is life only for God.
I call this life a happy one in which I do one good deed after another, with no intervals between them.
— Marcus Aurelius
We do good only when we do not notice what we do, when we forget ourselves and live only in others.
