温故知新 or “On Ko Chi Shin” roughly translates as “study the old, understand the new.” It is a maxim found in all martial arts. My sensei would say “keep one foot in the past and one foot in the future.” At the time he was referring to “a true” kobudo application of a defensive maneuver involving multiple assailants with implements of minor and mass destruction. They say the old ways Okinawan Karate have been erased with time.
I don’t believe that. Neither should you.
