.....and the God of Gods created the soul, fashioning it for beauty.
He gave unto it the gentleness of a breeze at dawn, the scent of flowers, the loveliness of moonlight.
He gave unto it the cup of joy, and He said, " You shall not drink of this cup save that you have forgotten (forgiven) the past and renounced the future."
He gave unto it also the cup of sorrow, saying "Drink that you may understand the meaning of joy."
