The prominence of particular organs and muscles shows the vitality which exists in these organs, and 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.
