One may view a marriage as two people standing back to back , each protecting the other in a particular way.
It is the feminine task to protect not only herself but her man nad her family from the dangers of inner world; moods, inflations, excesses, vulnerabilities, and what used to be called possessions. There are the things a woman’s genius can manage much better that a man’s. Usually he has his own task in facing the outer world and keeping the family safe.
There is a particular danger in the modern attitude in which both people face the our world, both spend their time in outer things. This leaves their inner world unprotected and many dangers creep into the household through this unprotected quarter. Children are particularly vulnerable to this unprotectedness.
When a marriage begins the partners are like two discrete circles overlapping a little. The division between he two is great and each has a specific task. As the marriage partners grow older, each learns a bit of other’s genius, and finally the two circles overlap more and more.
