Causes of symptoms according to Louise Hay is a good place to start if you are looking for healing. Illness however mild or severe is an indicator of your emotional state, caused by your thoughts and focus.

I first came across this concept about 11 years ago when i read You Can Heal Your Life by Louise Hay. I found this book while in the depths of depression and it turned my life around in the next few years. In this book Louise outlines the causes of physical symptoms and the affirmations one must repeat to heal the illness.
