To penetrate into the spiritual world, a thinking in accordance with truth is necessary. This requires a clear recognition of how things stand. Thoughts are real entities, and untrue thoughts are evil, obstructing, destructive entities. […] The ideal, which the man of today should set before his soul, is to be true; for thoughts are realities, and true thoughts are beneficial realities. Untrue thoughts — however well they may be enwrapped with the cloak of leniency as regards their own nature, — untrue thoughts received into man’s inner being, are realities which retard the world and humanity.
