A phenomenon which arises when the natural scale of male and female frequencies is thrown out of balance. The effect is to cause men and women to become attracted to and by partners who initially and superficially appear to be compatible but who, on longer association, are obviously not. This leads to bad relationships and broken marriages. Paradoxical compatibility is now commonplace and is a significant factor in the present deplorable state of society. It is not possible to describe this phenomenon fully here, but the Culdian teachings deal with the subject in depth.
