Keeping our duality in harmony is an ongoing challenge. We need ego's self care and boundaries to stay safe and true to ourselves, AND we need the soul's ability to recognize our relationship to everything else. Some people call the soul self our "higher self", but I think that our higher self is actually the balanced integration of the two, with deep wisdom that comes from seeing without judgement or prejudice. From the point of view of us as spiritual beings in physical bodies, it makes sense that there is a need for an ongoing dance with those two aspects of our human nature. Perhaps thinking about this perspective can help us remedy imbalances when they occur by recognizing what aspect of ourselves we need to strengthen to restore congruence.
