Now I know that they are not really superpowers but more like ability's. If your mind is powerful enough you can make your body able to do extraordinary things. One ability I think Buddhism allows you to train for is a sixth sense of magnetism. Your heart has an electric field that is more powerful than your brains. Controlling the heart and understanding it within yourself would mean that your body would become a conductive for detecting other magnetic currents. This could be the aura people detect when they feel good or bad vibes unconsciously. Secondly once you have control of the electricity in your heart you would also gain control of the chi points (nerves). So what do you think. Are there other ability's people may gain from Buddhist practices.
