I've been practicing this technique lately that allows my metaphysical being to affect my physical being (i.e. my mind affecting my body).  For example, when I have a headache, I have been able to end the headache through thought.  I'm still not sure why that works, but it does.  Heartburn works much the same way, or, at least, following the same basic principles.  Everything from itches to muscle cramps, actually.  Anyway, I don't know why I just posted this.  Guess I wanted to say it to someone.
