I have heard George Ledyard talking about how him imagine lines of unbalancing that come out from uke's body (ex.ikkyo line..). But it isn't clear to me wich (and how many) of those lines are and their general disposition and direction over a human body.
I'm wondering if somebody knows if exist some images out there that depict those lines.
you are over-analyzing it. a systema exercise. have someone stand in a karate/kungfu/judo pose. then you walk around and see how many ways you can unbalance that person by applying force in certain direction. be creative. you will soon lost count how many lines there are. remember that a push in front is equal to a pull from behind; a push to left = pull from right; a kick in the nuts = soprano for life.
