How the body feels and how it moves...
If internalising movement makes a martial art soft or internal or whatever... Then blargh.
I've never been much for this hocus pocus and never will. Like someone said it should all be leading to the same place anyway. And to for me who has only practiced full contact karate it makes absolute sense that the more I train the more I end up focusing on movements that are far less visible upon external examination.
Or have I missed the question here?
