The Spiritual Hierarchies and their Reflection in the Physical World: Reality and Illusion, a lecture cycle of 10 lectures Given in Dusseldorf, April 12 - 18, 1909 (CW 110) combined with a collection of 5 lectures given in Berlin entitled "The Inner Realities of Evolution" or "The Inner Experiences of Evolution) (The first set of lectures have been re-recorded as of 1-7-08) Below is the original image found on the lectures page. The second image is the cover for the soon-to-be-published collected works edition by Steinerbooks. I recommend the new set as I had read the earlier set far too fast and then tried to doctor the recordings with my computer resulting in unwanted side effects). This later edition then, has 15 lectures total.
For your convenience, below is a zip file of this entire set of lectures. It does require that you have an unzipping utility of some kind on your computer. For you mac people this is built in.
