One hears it said so often: The literature of Spiritual Science available to us is written in such a difficult style; it demands such effort and such intense development of the forces of the soul if any real headway is to be made. “Well-meaning” people — the adjective in inverted commas — are always coming forward with the suggestion that difficult passages should be simplified for their fellow-men; they want to trivialise — this I say without inverted commas — what is written in a rather difficult style.\n \nBut it is of the very essence of Spiritual Science that activity should be demanded of the soul; that Spiritual Science should not be easy to master. For in Spiritual Science it is not a matter merely of absorbing what is said about one thing or another, but of how things are absorbed — by dint of effort and activity of the soul. What Spiritual Science has to offer must be assimilated with sweat of the brow. That is a sine qua non in the whole business — forgive the colloquialism.
