The prominence of particular organs and muscles shows the vitality which exists in these organs, and the lack of it is lack of energy in these organs. Therefore, the straightness of any organ suggests straightness in the nature, and curve, where it is natural, shows subtlety of nature, a point, wherever it is natural shows sharpness of nature, roundness makes for subtlety, and the oval form shows acute intelligence. Proportion of head and body and of each part of the head and body shows balance, and lack of it shows lack of balance. Every organ represents a certain part of man's nature that may have no connection with that organ. A particular mode of standing or sitting denotes a certain nature. Crookedness where there should be straightness shows lack of straightness in the nature. Organs which should be symmetrical and are not show lack of balance.
