“If you walk past a group of lethargic pupils, you can hit with a bunch of keys on the table, allowing you to produce a shock.
We must combat this irregular interconnectedness of the etheric body with the physical body by acting on the unconscious.
You will always have to find another way to shock them and evoke what they do not like to do. “ (Rudolf Steiner)
