The purpose of this set is to cultivate proper energy transference within one’s body/mind by applying Yin and Yang tactics at their most extreme.  While the set may appear to merely be a series of attacks that are then sequentially matched by a corresponding counter, practitioners are asked to penetrate the surface of the form in order to cultivate the necessary sensitivity to energy that is required for Aiki to actually occur.  Though it appears to be, the set is not just about countering counters with just one more counter. Each practitioner fluctuates along the spectrum of Yin and Yang according to his/her partner’s own fluctuation on that spectrum in order to provide the energy that is to be countered or the counter itself.  Yin is answered with Yang, and Yang is answered with Yin.  Each move must reach its fruition while each practitioner seeks a non-attachment toward that which came before or that which will come after.  Should a practitioner fail in meeting his/her own role, the set would halt at a previous tactical location with “defeat” falling there as well.
