Whether you believe in this sort of thing or not, this was a nice introduction to using pendulums to answer questions, find things, and do all sorts of fascinating bits of magick. I was recently given a lovely pendulum as a gift, wanted to read about the "proper" way to use it, and picked this from a few recommendations. A nice, fast read that gives information clearly, with few fanciful flourishes of the sort that tick me off when I read nonfiction metaphysical books.
