In the Maya mythology, the hero twins Hunahpu and Xbalanque are highly revered. Conceived from the seed of their dead father's severed head, they grew up to be ballplayers like their father and uncle. Because their father and uncle had been killed in the Underworld after losing in a ball game, the twins grew up knowing they needed to avenge those deaths. Once they reached adulthood, they did defeat the gods of the Underworld and eventually were transformed into the sun and the moon.
I think this points to a deep truth, which is that in order to fulfill our destiny with our Twin Soul, we must defeat the shadowy, dark parts of our personality. In healing those hidden parts, we become "in-lightened" and ready to reunite with our Twin.
