On Knowing Oneself
O image of God, recognize you dignity; let the effigy of your Creator shine forth in you. Purify yourself, train yourself in godliness, and you shall find the kingdom of God within you. To yourself you seem of little worth, but in reality you are precious. Be wholly present to yourself and employ yourself wholly in knowing yourself and knowing whose you are, and likewise in discerning and understanding what you are and what you can do in him whose image you are.
