Four Basic Principles of Mind and Body Unification
Keep One Point

Keep One Point
The One Point is not a physical place in the typical sense of the word, but rather a point within the body upon which the calm mind may focus. It is really a state of mind.People often talk about the One Point being 2 - 4 inches (some measure it as precisely as 10 centimeters) below the navel. Such attempts at objectively describing a state of mind miss the point (no pun intended).By calmly focusing the mind on the lower abdomen, one becomes centered in the truest sense of the word. Physical movements, such as walking, are much more coordinated, while at the same time being very powerful. One may think of the One Point as the center of the universe. Since the universe is infinite, there is no single "center", but rather infinite centers. Thus, each person's One Point is the center of his or her universe.This universal mind/body centering creates a very powerful and calm feeling, which is very conducive to performing aikido. There are several tests which may be used to demonstrate whether a student has devloped the ability to keep One Point, such as standing in hanmi (normal aikido stance) and being pushed gently by a partner on the upper chest, shoulder, and small of the back. If One Point is being maintained, it will be relativlye diffcult to move the person being tested. The position is maintained by simply holding your place, not by resisting through pushing back.
Ki is a Japanese word which translates to, among other things, energy, spirit and power.In aikido, extending ki means extending energy. However, it does not mean to simply push with physical force. Rather it is a state of mind used to align the body to permit movement in a unified and calmly concentrated fashion.The classic illustration of ki extension is the Unbendable Arm test. The arm is extended in neither a rigid nor limp manner, but with a feeling of lively energy coursing through the arm from the One Point and extending out to infinity through the finger tips. This mental image produces an arm which is soft and pliable to the touch, but which is very difficult to bend.This feeling of dynamic energy extension is used in all aikido techniques. Without it, throws quickly become exercises in muscular tension, largely dependent on mere mechanical advantage and bulk.
Principles of the Body
The remaining principles, relax completely and keep weight underside, are principles of the body. although the mind initiates the "body feel", the primary focus of these principles is the state of the body.
This is probably the most misunderstood of the four principles of mind and body unification. Complete relaxation in the sense in which it is applied in aikido is not the relaxation of a lump of jello, that of the "dead" relaxation. It is instead the sense of a body full of energy without tension.Complete relaxation goes beyond simple muscular relaxation into mind/body relaxation. A calm mind naturally produces a calm body. Removing stress from the body greatly enhances freedom of movement, which is so necessary in aikido.
Keep Weight Underside
With all objects, weight naturally falls in the direction it is pulled by gravity, namely down. In human beings, however, it is possible to influence the manner in which the body "carries" its weight.The human body is not solid in the strict sense of the term, but is instead fluid. As water moves within a glass, so may the parts of the body "float" in relationship to one another.If one concentrates on the weight of the body being underside, or in the lower portion of the body, one finds that the body is very stable. if one concentrates on the upper body, of example the top of the head, the body becomes weight upper side and, as a result, unstable.When moving in aikido, it is important to keep your weight underside. This happens naturally if you are calm in mind and body, whereas tension automatically makes the body weight underside.
