This video covers bunkai for the juji-uke sequence of Pinan Godan / Heian Godan, and a variation on that sequence. It was filmed in Denmark at a seminar in November 2014.
It is always important to remember that every kata motion is essentially an illustration of principle. It is not the technique that is the end result; it the integration of the principles encapsulated by the bunkai of the technique that is of greater importance. That way the methodology of the kata can be applied in a habitual / intuitive way regardless of specific circumstance.
