King Lindorm and the split
The most clear example is midway through the story where the two kings leave the castle (the familiar, ruling patterns and identities) for war, leaving the women to rise the child. The masculine explores and gets to know itself through war, active engagement with the wider world, and the feminine explores and gets to know itself through motherhood, through nurturing at home. The split, the separation of the two (separatio) is necessary for both sides to find space to explore themselves, and then their relationship.
So there is a (mostly) unconscious wholeness/unity, a split, an exploration of each pole of the polarity separate from the other, an exploration of the relationship between the two, and then a conscious wholeness.
This is a pattern that seems to run through this existence, at all levels, from Existence as a whole (differentiated into awake emptiness and form) to our lives as who (individuals) and what (Spirit) we are, and in every aspect of our lives - all of the many polarities of our lives.
It is also interesting to note that the conscious wholeness happens at two levels: first, by noticing the whole of the polarity which is always and already there, and then in the conscious way the poles of the polarity functions on their own and in relationship with each other. The first is always there, the second comes through the work of differentiation, exploration and clarification.
