Ki is a very complex word... and even more difficult to translate to westerners. - Koichi Tohei

Just as tops spinning violently and rapidly becomes steady, the most rapid movements results in calm. Like the eye of the typhoon, which, is always peaceful, inner calm results in great strength of action. Calm and action are exactly one. Only when we keep our one point and unify our mind and body, can we find spare time even when we are busy. Keep a calm mind and you will be able to perform to the best of your ability, even in an emergency or when facing important tasks.

We begin with the number one in counting all things. It is impossible that this one can ever be reduced to zero. Because just as something cannot be made of nothing, one cannot be made from zero. Ki is like the number one. Ki is formed from infinitely small particles, smaller than an atom. The universal ki condensed becomes an individual, which further condensed becomes the one point in the lower abdomen, which in turn infinitely condensed never becomes zero, but becomes one with the universe. Thus we understand the essence of ki.

Ki tests are not founded on the idea of testing for strength or weakness. The most important factor in ki testing is to accurately inform the person of the state of his or her mind. Thus, the person performing ki tests must truly understand and exhibit oneness of mind and body from the outset and then perform the tests correctly.
