!-- Having no colour, no odour and no shape, the mind is not something that can be grasped by the senses. However, based on the principle that the mind and body are actually one, we can know the state of this ungraspable mind by testing the body, which is available to our senses. --> 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.
