I love the writings of Charles & Myrtle Filmore. Their grasp of metaphysical concepts was remarkable. Myrtle Filmore was a sweet soul who wrote inspiring messages that are still very applicable today.
This is a great book. As a Unitarian and a member of a Unity Church, I enjoyed reading this book by the co-founder of Unity. I particularly found her description of healing herself early in her religious life helpful. As an adjunct to other ways of taking care of yourself and whatever health issues you may have, it's a great tool to learn. She is an inspiration regardless of your faith.
