Generally, our health depends on our attitude to life. I think that anything happening in the body is an expression of the mind. The body is an expression of the mind; how the body appears is an expression of the quality of the mind. This is what I think. So, how much you take care of your mind determines how much you are able to take care of your health. Lama Zopa Rinpoche http://www.lamayeshe.com/article/bodhicitta-best-medicine
