Atom Weight Of Good

Someone asked: “The eternal decrees that God has predestined, do they ever change?”
Rumi answered: How could God say, “Do evil to find good?” If someone sows wheat, can they gather barley? Or if they sow barley, will they gather wheat? That is impossible. All the saints and prophets have said that good is the reward of good, evil the reward of evil. "
And whoever does an atoms weight of good shall see it,
And whoever does an atoms weight of evil shall see it."
