I. The Origin of Suffering

This also underlies the expression of the Greek poet: Out of life grew learning; out of learning, knowledge. Here again, as already mentioned in the previous lecture, a knowledge based on the most recent research of natural science touches the results of old spiritual investigation. The older spiritual research has always said that the highest knowledge can proceed solely from suffering. When we have a sick limb and it has given us pain, then we know this limb best of all. In the same way we know best of all what we have deposited in our own soul. Knowledge flows from our suffering as its fruit.
