Kurt was (is?) a member of this forum and is a book author and expert on AP and spiritual self development in general.

Just yesterday finished watching his video, it's mostly on Annie Besant (Theosophist), he also wrote a book about her, but it's also on types and paths of spiritual development from a theosophical viewpoint.

I found it interesting and worthwhile. It's sad that Korpo/Oliver isn't here anymore around on the forums, as far as I remember and know for sure he also would like this video very much.
