How Does One Attain Knowledge of the Spiritual World?

As I said, I do not wish to present this here as a personal matter in an importune way, yet it seems to me that just in such a gesture the position of the best human beings of our age towards the spiritual world is epitomised. Because later I had a long conversation with the same Hermann Grimm on a journey that led us both from Weimar to Tiefurt. There he explained how he had freed himself entirely of a purely materialistic view on world events, from the opinion that the human spirit, in the successive epochs, would produce out of itself that which constitutes the real soul-wealth of man. At that earlier time Herman Grimm talked about a great plan that was part of a piece of work that was never realised. Those of you who have occupied themselves with Herman Grimm will know that he intended to write a ‘History of the German fantasy’. He had envisaged the forces of fantasy to be like those of a goddess in the spiritual world who brings forth out of herself that which human beings create for the benefit of world progress. I would like to say: In that lovely region between Weimar and Tiefurt, when I heard these words from a man, whom I, after all, acknowledge as one of the greatest minds of our time, I had a feeling that I would like to express in these words; ‘Today, many people say to themselves: One must be deeply dissatisfied with everything that external science is able to say about the sources of life, about the secret of existence, about world riddles—but the possibility to step powerfully into another world is missing.’
