In one region of the soul every human being has a natural aptitude which in all other areas it would need considerable effort to gain supersensible knowledge about. And this one area is when a loving relationship is entered into between human beings. People must learn to develop this skill in relation to other contacts and approach them in a similar loving way with understanding and instinctive interest and a genuine desire to get to know their inner being better. In the instances that we approach other human beings with inner participation, with deep understanding, with true interest, in those instances we become, if I may put it this way, clairvoyant in everyday life.
