Natural Intelligence
Every learning, every spiritual elevation, must be built on the foundation of natural feeling and natural intelligence. And natural intelligence itself with all natural feelings in a good measure of their stance—must be in their beginning planted on the foundation of the holy of holies, which carries within itself the load of the holy and the load of the secular, the material and the form, in a form that is uplifted and ideal, in an elevated unity.
