Before The Secret made the Law of Attraction a household name, a group of metaphysicans were writing about how thoughts are things and what you think you are. It was through reading The Secret that I discovered Thought Vibration by Mr. Atkinson. Thought Vibration is not the best written book, but the information it offers is good and timeless. I recommend that serious students of truth or esoteric wisdom read this book to get additonal information on thought vibrations.
This book is a great tool to learn how to focus your thought energy and become a deliberate user of the LOA.
