According to Osho, heterosexual love is troublesome precisely because it unites opposite polarities—man and woman—who are drawn together by difference yet speak different inner ‘languages’ (logic/illogic, left/right brain, far/near). This creates cyclic closeness and distance and unconscious power struggles (muscle versus tears). And it isn’t new; it’s intrinsic, biological, as old as Adam and Eve.
Boys and girls are very different, so they like each other but often don’t understand each other, which makes fights normal and very old—not a new problem.
