Living a good life leads to enduring happiness. Goodness in and of itself is the practice AND the reward.
EpictetusNo living being is held by anything so strongly as by its own needs. Whatever therefore appears a hindrance to these, be it brother, or father, or child, or mistress, or friend, is hated, abhorred, execrated.
EpictetusWhen you close your doors, and make darkness within, remember never to say that you are alone, for you are not alone; nay, God is within, and your genius is within. And what need have they of light to see what you are doing?
EpictetusKnow you not that a good man does nothing for appearance sake, but for the sake of having done right?
Epictetus
