Re: Terms: I.S., I.P., Neijin, Fajin, Aiki, etc.
Walking back from the grocer's just a moment ago, I thought of a big point that differentiates the "internal" methods from "external" or "non-internal" forms. And that is that attacking methods in the "external" forms like most karate (I won't say "all" karate) cause damage to the outside of the opponent's body in order to damage the inside of his body. But internal forms can damage the inside of the opponent's body without making a mark or causing clear damage to the outside of the body (i.e., rupturing internal organs without breaking the protective bones around them).
What do you think?
I think that it's a separate discussion, David. I know *why* "internal strength" can do these things, but since I know it will be something "taught for the last 20 years" by some people, I leave it for them to explain now rather than after the fact.
