After completing his main esoteric work >Geheimwissenschaft im Umriss< in 1910, Rudolf Steiner kept looking for ever new ways of reshaping the linguistic and textual presentation of his Anthroposophy. In the monographs published in this volume, >Ein Weg zur Selbsterkenntnis des Menschen< (1912) und >Die Schwelle der geistigen Welt< (1913), he attempted to develop central aspects of anthroposophical thinking in the form of short meditation texts. The individual chapters of the texts represent, on the one hand, a theoretical contribution to the anthroposophical understanding of consciousness; on the other hand, they provide concrete instructions how to practically work on the development of consciousness.
