The Goju Ryu Technical series of instructional programs represent a important part of the legacy of this remarkable teacher. It is a time capsule, filled with the author's extensive knowledge, to be preserved for this and future generations—an immersion course in traditional Okinawan Goju Ryu karate of such scope and intensity that it eclipses everything that preceded it. Saifa and Seipai kata were chosen as the subjects of this, the first of six volumes in the series, as they are the Goju Ryu kata most frequently learned by students of other styles of karate. With this in mind the author, in his demonstrations, pays special attention to the core concepts of Goju Ryu such as synchronised breathing and the harmonising of hard and soft, that the viewer might not be familiar with. This program was filmed in studio using four cameras to give the clearest possible view of the movements and applications of the kata. Slow motion is used extensively to reveal subtleties of technique, many of which are explained by the author in great detail in his lectures. Well organised navigational menus make this program a delight to use, and the superbly edited sound track and attractive graphics are the hallmark of its production team that is the most celebrated in the field of martial arts instructional programming.
