Nooo cold neutrality IS good. For a technique. What I mean is that it should be up to us to add our OWN warmth to it, if we so choose. I find if there's too much love in something it can be kind of offputting because it's not the kind I relate to.

Zen Buddhism was popular among the warrior class of Japan I think, and I guess they could be somewhat stern at times. I think there are probably some that laugh, but perhaps they see it as a lack of discipline or respect to do it on grounds. I read a book on it and even I don't understand it too well...
