She is being pierced in the stomach with a glowing-hot needle when it happens.
Past and future fall away: there is only the now. Soul and body are one entity, to the point where it is meaningless to think in terms of soul: there is only the body. What her body feels is pain. And pain is a delight. She had felt it, a little bit, when she used to cut herself. But not in this overwhelming way, this tidal-wave rush of sensation she no longer fears but welcomes, yes, all the way in. Take me. Do what you will. It doesn't hurt at all, it's ecstasy. Why did I ever fear it?
She laughs as they put more needles in. She's happy.
