Here is a powerful idea from the book, which has been very helpful to me: "I accept myself completely here and now, and consciously experience everything I feel, think, say and do as a necessary part of my evolution into higher consciousness."
The author's analysis of the 3 unhappy levels of consciousness is extremely useful and clearly articulated. His writing is distilled to the essential ideas, and is worth reading repeatedly.
Keyes is just plain right. The more I look at my consciousness, the more clear it is to me that his formula for happiness (or peace of mind) is correct.
His primary point is that if we can simply let go of these primary thought patterns, whether they be about security, sensations, or power, then we can be happy. The full meaning of those terms is lucidly explained in the book.
One little thing: I'm not sure about the name of the "power" center of consciousness. When you work with this book, one of the activities is to try to always be aware of which center of consciousness you are using. Very often, I found I was (am) in the power center, but for it to be real for me, I had to expand the concept to include everything to do with "self", in the sense of feeling one's worth or esteem, especially in relation or comparison to other people. Perhaps it could have been called the "Self" center (Or the "small self" center). Maybe that's no better. Ken, what do you think?
