How to Gain Knowledge of the Higher Worlds
GA 10
Translated by Steiner Online Library
Preface to the Eighth to Eleventh Thousand (1918)
[ 1 ] Only minor changes seemed necessary to the contents of this new edition of the present book when I worked through it again. On the other hand, I have added an "Afterword" to this edition, through which I have endeavored to say some things more clearly than before concerning the spiritual foundations on which the messages of the book must be placed so that they can be received without misunderstanding. I believe that the contents of this epilogue might also be suitable to enlighten many an opponent of anthroposophical spiritual science that he can only maintain his judgment because he imagines this spiritual science to be something quite different from what it is; while he does not even consider what it is.
