Things of clay may be loosely defined as the temporal
, the bits of your life that you desire
but really do not add significantly to who you are as a person
Money,fame,praise, these are all things made of shadows, and a person of virtue should not seek them. Do you desire that woman? Your desire is clay. The woman is clay. It will wash away in a hard rain.
Seek instead love, the respect of your community, the sense that you, that you that dwells below your desires, will not wash away when that hard rain comes to you.
