Of late I have been examining the nature of working the edge of an encounter with uke. I define the edge of an encounter as a point at which my energy and ukes energy cancel each other out and our meeting becomes push/pull free. The objective of working the edge is to extend the point of equilibrium continuously through the entire encounter, stretching it, as it were, to form an edge along which uke and I move.
Working the edge, along with my occupying the epicenter of our combined motion, allows me to simultaneously lead and follow uke while guiding him into a state of unbalance which will give rise to a technique that's derived logically and naturally from our interaction.
