4. The Human Soul and the Human Spirit
This is the source of endless misunderstandings, because time and again what has been described as true clairvoyance is confused with what in trivial life is so often called clairvoyance, clairaudience and so on, but which is due to some defect in the physical organism. One can have such a defect or cause it oneself through all kinds of unnaturalness, in so far as it is also easier and more convenient to achieve what one confuses with what can be achieved through a further development of healthy human perception. It must be expressly emphasized that overcoming the sub-sensible behavior of the soul is precisely what is achieved in the very best way - much healthier than through common sense - precisely through true clairvoyance and true clairaudience.
