The force will protect you.

[Luke:] I can’t believe it.

[Yoda:] That is why you fail.

Erm. What I mean to say, is all you have to do is believe.

From Neurotopia:

Woo also permeates the martial arts. If one's chi is properly aligned, supposedly the practitioner can make their body do amazing things such as selectively exploding an opponent's internal organs when struck, or sometimes inducing a time-delayed killing sickness. My old kung fu instructor even tried to demonstrate that chi existed by having us hold our hands right up next to a mirror after a workout, supposedly when our chi is flowing maximally. He claimed you could see the visible effects of chi which manifested as a mist traveling up the mirror away from our hands. He was right: the mirror did fog over. I imagine it had more to do with the mirror being at a significantly lower temperature than our hands, which were sweaty and radiating heat, which caused condensation to appear on the mirror and radiate upward away from our hands with our body heat. Oh well.
