The success of a marriage depends upon the relative values of four variables – really, two instances of two variables, one instance for each partner. Let’s call S the Shadow, that part of the self where wounds hide (some call them defects of character; I call them wounds). Wounds are revealed, first to oneself and then to the other, in an act of intimacy. Then let E stand for Enlightenment, a common word for maturity in many spiritual traditions. Carl Jung and others called it individuation. The “light within” that comes through spiritual and psychological maturity (wisdom) illuminates and integrates one’s shadow into the whole person (healing). In marriage, enlightenment provides visibility and calm when your partner’s shadow is cast over you.
Each partner has wounds, more or less, and each partner is enlightened, more or less, which makes for two instances of these variables. Thus we have Shusband and Swife, Ehusband and Ewife and the marriage predicate is:
(Ewife > Shusband) & (Ehusband > Swife)
E > S means that one has enough enlightenment to stand in the other’s shadow with equanimity and compassion. Put a different way, one can hold the other without becoming overwhelmed, offended, defensive, resentful.
This “equation” might seem rather obvious, but here is the real point. Nowhere is it stated what are the literal values of E and S. There is no cultural standard value of E or S. There is no threshold above which you can say, “Well, her shadow is obviously too dark” or below which you can claim, “He is a certified dimwit.” The variables are always relative – too dark for his brightness, too dimwitted for her shadow. Without objective standards there can be no blame.
Instead of deciding who is on the wrong side of the non-existent human norm, the way forward, either within the marriage or after the divorce, is two-fold. Grow further towards enlightenment and integrate more of your shadow. A couple has to meet each other half-way in this work. A newly single person wants to be in a better position for the next time.
