Body Lines

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.

Like playing pool - must line up que stick, que ball, ball, pocket, etc. And in three dimensions, and all in motion.

When we were toddlers, we normally drew pictures of stick men. o-<-< The lines apparently in those drawings are those imaginary lines for a person's ki (except for the head which is normally drawn as round) It rather looks more like this --<-< Well, you would think it may sound uber simplistic and probably laugh but it is an accurate representation of the lines of ki. It's better this way in a sense since you dont need to overcomplicate things. Also, it took me decades to realize (ie stickman) this was the case but that it works as a model.

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.

I'm not sure if this is what Ledyard Sensei is talking about but I reference "vectors" in conjunction with body position. For instance, Kamae may be very strong or have a strong vector from the front but from the side there is a weak vector where one may be easily unbalanced.

Thinking about the weaknesses in the stance, and applying the correct angle to topple either by pushing into or pulling on uke and doing Phi suggest sounds good.
in this i think aiki is an energy minimisation problem - what is the least energy required and the optimum angle/ direction to apply it. I started exploring it as a blog, its gets messy pretty quickly but i found some neat insights that helped my practice and ways to critically view video footage. might be something of use and happy to receive feedback on what is quite unfinished/un polished
