Re: "stance of heaven (and earth)" and IS
"Internal power" is a vastly overloaded term. Chris is telling you that when people here on Aikiweb use the term these days, they are talking about something quite specific, which has little relation to what you're saying. This isn't good/bad or right/wrong, necessarily--it's just a different topic altogether. And it's not about what's the "right" meaning of the words--though you can have that argument if you like. You're just being warned about how people have been using the words lately in this community. Many of the flame wars we have had have been fueled by some people using the term in a very specific sense while others use it much more generally.
So tell Chris thank you and keep your eyes open because when people respond they are likely to be responding from this different standpoint.
