Conny Mendez firmly believed in metaphysics for everyone, and dedicated a significant portion of her life to teaching spiritual truths in plain simple terms that anybody can begin to apply in everyday life. One of her most important, prized, and popular books is El Librito Azul, or The Little Blue Book.

It is a compact and concise read that is designed to be carried and read on a regular basis, until its laws and principles are second nature for the reader. This book can show even a young child of average intellect how to combine laws of thought with spiritual truth, producing the fruits of what can best be described as "a life truly worth living."

By popular demand, The Little Blue Book has been revised and updated for the busy 21st century reader, while painstakingly preserving Conny's masterfully-written legacy as faithfully as possible.
