I like this, actually it is very applicable to martial arts, in a Tai Chi theory book and my tai chi class, I read that we are equatable to trees in that, from the earth our feet are rooted (or if you are very good you can be rooted in the air) giving us balance and energy, and this balance manifests, from feet, to knees, to hips, to abdomen, to chest, to shoulder, to elbow to arm and maybe even fingers. This martial teaching really shows you how each part of the body is integral in martial sciences. Just as a tree needs roots trunk branches to make fruit or leaves.
Also in meditation I learned in standing that we are to draw Qi from the ground through us.
Very cool thought
