Query: A must for the practical magician

I just discovered this author's works recently and already I'm impressed by the depth and breadth of his writing as well as his attention to detail. Magical Techniques provides information on lesser known magical practices and tools that can be used by the magician to aid and enhance his/her workings. From his chapter on how to make chalk, to how to use feathers, to magic with orgone accumulators, there's something for everyone. He also provides some good anecdotes, both his own and of other people and how they used the different tools he discussed. This book is a definite must for the practical magician.
