Yes. A friend of mine who is an author is in a wheelchair, can't speak, can't write, can't move, and can't even feed himself. He doesn't feel sick. He doesn't see sickness. If you are seeing sickness, you believe in sickness which also means that you believe in good and bad. You believe in a good god or a bad god. I believe that we can heal ourselves from sickness, because it's just like that nervous stomach response. My friend doesn't see himself as a boy trapped in a wheelchair. He does not feel victimized. He does not feel sick. He seems himself more whole than any of us do. I have seen people even in my spiritual psychology program who change their diabetes or fibromyalgia because of the way they think. You can get into all sorts of debates and arguments, but if you think sickness you believe in sickness.
