One finger of Zen Meditation?

Hey guys. I was poking around Stumbleupon, and brought me to a wiki page with a large list of Shaolin arts. The one that intrigued me the most though, was the One finger of Zen Meditation.

Here is the site: http://en.wikipedia.org/wiki/List_of_the_72_Shaolin_martial_arts#cite_note-Zhong-0

Mind you, there are many arts on there that look awesome, but this one says if you practice it, you can extinguish lamps and such from a distance?

My question is, is this a load of BS, or does someone here possibly practice this, or has maybe seen it?

Thanks!
