Another beginner's question! I hear the terms koppojutsu and kosshijutsu a lot, and I'm wondering what they mean. The idea of "bone breaking art" is apparently a mis-translation or something, but what is the feeling or essence of it? Is it part of the ryu? If so, which ones? I went to a seminar this weekend where it was discussed, and much of it went over my head. Thanks for what might be a dumb question!
