Love, joy, and peace are deep states of Being, or rather three aspects of the state of inner connectedness with Being. As such, they have no opposite. This is because they arise from beyond the mind. Emotions, on the other hand, being part of the dualistic mind, are subject to the law of opposites. This simply means that you cannot have good without bad. So in the unenlightened, mind-identified condition, what is sometimes wrongly called joy is the usually short-lived pleasure side of the continuously alternating pain/pleasure cycle.
