In other words it is a tool for taking three factors, unifying them and creating a oneness out of all three. Perhaps the most general and inclusive example of this is:
[ (Love x Grace) <-> Wisdom ]
You could also make that
[ (Love x Grace) <-> God ]
You could go further and make a Trinity-Unity-Oneness (TUO) out of the integration of that Duality:
[ [ (Love x Grace) <-> God ] x [ (Love x Grace) <-> Wisdom ] <-> Cosmos/microcosm x macrocosm ]
