Yeah, Jung figured out a lot of good stuff including one of the most core teachings: the Hieros Gamos or Alchemical union of opposites. He covered it in The Mysterium Coniunctionis. Every tradition has this concept whether it's God/Holy Spirit/Christ, Osiris/Isis/Horus, Chi/Rho/Phi, or, as is often the case, the third spot is left blank as it is in the cases of Fu Xi and Nu Gua, Damballa and Ayida Weddo, Yin and Yang, Alpha and Omega and many others. I call it "the Perennial Holy Trinity": the Divine Feminine unites with the Divine Masculine within a person. This is essentially a self-birthing of the Divine Child or enlightened being. He also figured out that archetypes are important and that we each use one another as mirrors. Everyone is a guide, but people tend to be mixed bags of attractive guidance and repellant guidance.
