In Berlin, just past the turn of the twentieth century, Rudolf Steiner, then a relatively unknown writer, educator, and editor, first began his spiritual teaching activity under the auspices of the Theosophical Society. The gatherings at this time were small, often being held in private homes, and therefore, in terms of size and location, intimate.

Immediately after assuming leadership of the German Section of the Theosophical Society, Rudolf Steiner began a comprehensive program of teaching, at first within the Berlin Branch of the Theosophical Society. The notes from nineteen of those early lectures and four private lessons form the content of this volume.

Moving back and forth between Eastern theosophical terminology and Western esoteric tradition, searching for words and pictures, for the first time Steiner was presenting the results of his spiritual-scientific research to small groups of people longing for deeper truths.
