Besides the attraction of like to like there is the law of attraction of each to its opposite. There are two great forces in nature: the creative force and the receptive force that answers to it, or the active force and the passive force, Jalal and Jamal. This can be understood from the law of rhythm. In every rhythm there is the stronger beat and the weaker beat, the returning. In two-four time, for instance, we count one-two, one-two, the strong beat and the beat that has just as much force as to counterbalance the other.
