On Chakra...

Here are a few links of interest on Chakra:

Wikipedia: Chakra

Naruto: Chakra

The first one's of use, the second one's not so of use. Hehe. I love Naruto by the way... If you don't know what it is, you have no idea what you're missing...

By the way, just thought I'd mention that Chakra's got a more kinky side to it then just arty farty theatre... It's exotically esoteric... He (or she) who is in control of his (or her) Chakra is in for one heck of a fucking good time... (read in between the lines... come on...)
