Speaking from a metaphysical point of view, if you can change your perception of pain, you can transcend it.
If you can change the meaning you have attached to pain and DETACH from the fear the human mind has learned to attach to pain, you can move beyond it.
If you were to thank pain for pointing out to you what area of your life you are needing to pay attention to, you would associate a good feeling to pain rather than a negative one like fear.
Pain is often not what holds people back from healing. Instead it is the fear and the whirlwind of attracting negative emotion through like thoughts that is ultimately what destroys the being and renders it assuming it is helpless.
