Secret Brotherhoods and the Mystery of the Double, seven (plus two) lectures given in St. Gallen, Zurich and Dornach between 6 and 25 November, 1917 by Rudolf Steiner (CW 178). The collected work has actually 9 lectures and since I have previously recorded the other missing two, I included them at the end of the book for convenience. Their original location on this site is the title Psychoanalysis and Spiritual Psychology. Translated by Johanna Collis.
