XXIX. The Essence of Egoism (Goethe's “Wilhelm Meister”)
Now, in the etheric body, how is the activity [through a too strongly acting ego]? It asserts itself through the possibility of error on the one hand and of lies on the other. Man is subject to error because the ego works too much in the etheric body, not in harmony with the outside world. Now, and the lie? When we lie, this thought form is formed as a real fact, and in the spiritual world there arises what we call an explosion in the physical world. If the I did not merge in the etheric body, the person would know that what is not in accordance with the truth, with reality, causes destruction, an explosion. We have to take this into our karma, destroying our life's journey until we have balanced it again. A liar destroys as much in his karma as bomb explosions in the physical world. Lies and errors are caused by the ego asserting itself too strongly in the etheric body.
