In my -humble- opinion, the "Magic of the Future" (or; the "Magick of the Future" -as I like to name it (and also; as it is also known)- course, is one of the best course in this theme, and one of the best what I have read (beside the books of Eliphas Lévi, Papus, Agrippa von Nettersheim, Johannes Faust, Guido von List, Maria Szepes, Victor Sharon, Yliaster Daleth, Lui Padre, Chuck Cosimano, Franz Bardon, etc., etc.).
Reading- and studying it, the puzzle pieces fall
into their -correspondent- right places.
I consider, that it was one of the best investment I did more than 20 years ago (in 1998) when I order it.
