Llewellyn's Little Book of Pendulums by Richard Webster

Richard Webster introduces pendulums as tools for divination in this compact guide. The book includes exercises and explores applications such as energy work and the search for lost objects within the author’s spiritual framework.

It is a book about dowsing, not a pendulum supplied with the purchase. Pendulum responses do not provide reliable medical or mental-health assessment, and its proposed applications should not replace practical searches, evidence or professional advice.
