If you want to be healthy you dont have to follow any religion to discover physical health. All you have to do is follow the laws of Nature instead of rebelling against them, and your body will enjoy good health. This Earth reaps its rewards to every living thing on it - no matter if you believe in its Creator or not.
If you want to go a step further and experience the best emotional/spiritual healing you've never imagined then seek out the Creator of this Earth, and He will meet you halfway.
You will never be the same again and will see how all three- spiritual,mental, and physical health all tie in together.
