The Ten Chi Jin Ryaku no Maki is based on the three levels of life: heaven, earth and man. Man is the link between earth and heaven or between outer space and the planet. The old Chinese pictogram is a drawing representing two opposite half circles linked by a cross. The pictogram displays symbolically a human body with his legs on the earth supporting the sky with his arms, and mixing these two influences within his body.
What are the different parts of the Ten Chi Jin?
The Ten Ryaku deals with footwork, distances and angles; this is the vertical line in the pictogram. The Chi Ryaku deals with the bio-mechanical aspects of the different waza that can be applied once uke has reached tori (gyaku, nage, torite). This is the horizontal line. The Jin Ryaku is a series of about 50 waza taken from the nine schools to show the interaction of the waza and the footwork. This is the point where the vertical and horizontal line cross each other.
The Jin Ryaku has nothing to do with the schools. The waza taken from the schools are often quite different from the waza included in a certain level of a school. They are used as examples to manifest the interaction of body movement and creativity.
This is why they can be trained on both the left and right side and why they do not imply the use of weapons.
