Man does not become sick in part. The whole of him becomes sick: body, mind and spirit. The body will manifest symptoms of the illness, but the physical body is not the origin of the illness. At death, the physical body remains, but it is no longer curable. That which is curable has left the body. The vital force has left the body. An imbalance in the vital force is the origin of the illness. The symptoms expressed by the body, the mind and the spirit are simply the signposts telling that of imbalance. Homeopathic doctors use those symptoms to select a remedy especially for that person in his illness, but the remedy is a potentized substance having an energy force. That energy force acts on the vital force. Once the vital force returns to balance, the person heals himself.
