Lecture II
When the human soul takes on the task of making itself capable of looking into the spiritual world and gaining insight there, it takes on itself, more than anything else, a task that otherwise is carried out by the subconscious guidance of soul life. Nature and its laws take care that in everyday life man does not often transfer the customs and regulations of one kingdom into another; the natural order would be entirely out of control if the separate worlds were to get mixed up together. We emphasized a moment ago that love for the spiritual world must evolve in such a way that the human being develops in himself first and foremost an all-pervasive inner strength, as well as a craving for self-improvement. He has to fix his eye on himself when he nurtures his love for the spiritual world. If, however, he transfers to the senses the kind of ardour that can guide him in the spiritual world to what is most sublime, it will lead him into what is most detestable. There are people who have in their outward physical experience and in their everyday activities no special interest in the spiritual world. It is said such people today are not uncommon. But nature does not permit us to use the ostrich strategy in her affairs. The ostrich strategy, as you know, consists in the bird sticking his head in the sand and believing that the things he doesn't see are not there. Materialistic minds believe that the spiritual world is not there; they do not see it. They are true ostriches.
