The first essential for a teacher is self-knowledge. If for instance a child makes blots on his book or on his desk because he has got impatient or angry with something his neighbour has done, then the teacher must never shout at the child for making blots and say: “You mustn’t get angry! Getting angry is a thing that a good man never does! A man should never get angry but should bear everything calmly. If I see you getting angry once more, why then — then I shall throw the inkpot at your head!”
If you educate like this (which is very often done) you will accomplish very little. The teacher must always keep himself in hand, and above all must never fall into the faults which he is blaming his children for. But here you must know how the unconscious part of the child’s nature works. A man’s conscious intelligence, feeling and will are all only one part of his soul life; in the depths of human nature, even in the child, there holds sway the astral body with its wonderful prudence and wisdom.
