I think it is well proven that a person's spirit and the life of the Spirit within is a key, the key, to health of mind and body.
It needs to be two pronged. We seek to get rid of our defects and to strengthen and develop virtues. In AA we say that we seek spiritual progress rather than spiritual perfection.
What seems sad it that the virtues mentioned in this book are unknown to so many. They have never discussed them nor wanted to develop them within them.
Thanks for sharing this good thought provoking material.
