In 1909 Steiner had a series of discourses about the Cosmic hierarchies. In these early days Steiner was still under Theosophical influences and there is quite some Eastern information. Steiner gives his views that he obtained by clairvoyant investigation and this book is one of these which may be a bit over the top for people who are not familiar with Steiners way of getting and giving information. As always the information is very detailed and (at least to me) very interesting. Not the everyday things or even ‘every day spiritual information’, but something to use (or not of course) in your larger worldview.
