For example, observing the navel area of this Yogi: the direction of skin and hair growth movement is downwards, from the upper torso towards the navel, where all directions converge. Additionally, there’s a more energetic pattern coming into the center from the right than from the left.
The patterns are like fingerprints, each person's torso possesses a unique pattern. What might create the pattern on a body's surface...a particular physical practice? Genetics? Temperament? Posture? Age? Trauma? Happiness? The soul pushing up against the inside layer of skin?
Skin patterns can sweep from right to left, or visa versa; some bodies have scars visible only on the plaster body cast but not on the flesh. A few, but not all, reveal an upwards moving fountain pattern that connects navel to heart.
