Anger and stress kills the body. When looking at an illness and getting to the root of why it is manifesting in the body and how the illness is serving you, one of the best places to look is at underlying anger. It may not even be immediately noticeable. Anger may be running in the background like an app on your cell phone. Running, using and draining energy. While discovering why your body is manifesting an illness, no matter how small or large the problem may be, here is something very simple to say to yourself as many times as you need to during the day.
All organs, all systems in my body always function properly. They are functioning properly NOW.
Also, before you go to sleep, ask your higher self to reveal to you the root cause of your illness. Do this nightly as long as you need to and keep a dream journal. It may be revealed to you in your dreams, it may be revealed as an insight, intuition, or one of those ah-ha moments.
