Justice: This is a card of balance. When I pulled this card today, I felt this strong rush of, "stand up for yourself!". You can't placate someone into treating you better. You can't make abundance in one area by causing lack in another.
If something is a sacrifice, there has to be an equal gain, or it won't work. A relationship that compromises your sense of joy, of creativity, of full expression of yourself can't balance.
Notes on justice: don't defend yourself if you aren't on trial. Also, Justice is not always equal to the law.
