Life is, in its very essence and character, a terrible mystery—this whole business of living by killing and eating. But it is a childish attitude to say no to life with all its pain, to say that this is something that should not have been.
...acupuncture stops pain by stimulating the release of endorphins into the cerebrospinal fluid. We were able to demonstrate that it was indeed the flow of endorphins that caused the pain relief, because when we used an endorphin antagonist (naloxone) to block the opiate receptors, the pain-relief effects of acupuncture were reversed.
Pain and body image are closely related. We always experience pain as projected into the body. When you throw your back out, you say, “My back is killing me!” and not, “My pain system is killing me.” But as phantoms show, we don’t need a body part or even pain receptors to feel pain. We need only a body image, produced by our brain maps. People with actual limbs don’t usually realize this, because the body images of our limbs are perfectly projected onto our actual limbs, making it impossible to distinguish our body image from our body. “Your own body is a phantom,” says Ramachandran, “one that your brain has constructed purely for convenience.”
