I found this passage about Lancelot and Guinevere last night in a book I was re-reading by Heinrich Zimmer, The King and the Corpse:

One might say that the personalities of Lancelot and Guinever had become, both, entirely invaded and enchanted by the powers of the “lake” of the unconscious, possessed and beset, by a trans-personal, compulsive, unrationalized and rationally ungovernable animus-anima interlinkage. Their conscious individualities had been overwhelmed at first sight by an archetypal, rather than personal experience. Each had discovered in the other, not a devoted human companion, but the perfect counter-actor on an ideal super-human stage of abstract, yet fatal passion. Each was related to the other, not as to a human being, but as to a discovery of a lost, required, separated portion of a soul. They were not two, but one: each a projection of the unconscious of the other. And if their normal human biographies became annihilated in this demonic spell, that was because the timelessness of their relationship left little within them of time. Their charm held the world about them spellbound. And though it strewed the stage with disaster and disgrace, nevertheless, not even their closest intimates could presume to reproach them. In the presence of their representation of the timelessness of the two sexes in their experienced identity, all the proprieties, conventions, ideals and virtues of the court fell into insignificance. (p. 159-160)

This relates directly to a post I did about a week ago, in regards to finding certain types of people who set you off, because in them, you actually see a part of yourself which needs to be expressed. Read more here.
