I agree with the previous reviewer. I came upon Science of Mind in 2006, although I've pretty much been practicing a lot of the concepts since 1994, when I first discovered New Thought and metaphysical ideas. I found a real connection with SOM, however, and have bought every book by Ernest Holmes I could get my hands on. I have been searching for the entire "Change Your Thinking, Change Your Life" home study course for years. Since I don't live near any Centers for Spiritual Living, I've been on my own for studying SOM concepts at a deeper level. This series of books was designed for people like me, who don't have access to Religious Science centers, but still want to live this wonderful philosophy Ernest Holmes founded. I am already well into volume 1 and enjoying the lessons. Definitely a great course for the serious student of Truth. Please note, though, that you'll need a copy of "The Science of Mind" (the 1938 version) along with this, as it is heavily referenced.
Unfortunately, this series is currently out of print by the publisher, so it is difficult to find all 6 volumes, but worth it if you can!
