And unlike you, I chalk that up to the same thing. "Power" and "chakra" have been used interchangeably before, so I don't know why we bother differentiating this time, but it doesn't matter because it really doesn't affect the outcome of this discussion.

How can something with no explained meaning be used interchangeably?
