There is no knowledge more important than the knowledge of listening to our body for the sake of our own health. We have an illusion that someone from the outside can heal us. If anybody can heal us, it is only ourselves. It will take centuries for science to learn the hopelessness of the attempt to push the everchanging human body into frames of scientific theories. But it is possible to know what we need to do here and now for our health. It is possible to learn to listen to our body's voice.
