XI. Who are the Rosicrucians?

One incident that appears as a basic feature of various accounts can be summed up by saying that Christian Rosenkreuz—that is not his real name, but the one by which he is known—made journeys at the end of the fifteenth and the beginning of the sixteenth centuries. On journeys through the East he became acquainted with the book M————, a book from which, so we are mysteriously told, Paracelsus, the great medieval physician and mystic, gained his knowledge. This account is true, but what the book M————actually is, and what study of it signifies, is known only to initiates.
