By harmlessness is meant that though man does not seem to harm man in the way the animals of the forest harm one another, yet by keen study one sees that man can harm man more than the wild animals harm one another. For man is the outcome of the development of the whole of creation; therefore the ego, which makes one selfish, is developed in him more than in any other creature. Selfishness keeps man blind through life, and he scarcely knows when he has caused harm to another.
