| Spiral shape is also basic structure of consciousness. The way of thinking
of it is explained as follows.
Suppose there is spiral shape centering around a circle. (Please refer to Fig 11)
Shortest distance between central axis and spiral shape is constant. (Figure
is a little inaccurate)
Suppose rotation number of spiral shape is infinite per 1 rotation around
circle. So, one rotation component of spiral shape is nearly circle. In
addition, point on central axis is center point of one rotation component
(nearly circle) of spiral shape.
Suppose circle of central axis is degenerated into a point. (It is called point A). So, center points of every rotation (nearly circle) of spiral shape are consolidated into point A.
At this time, spiral shape is converted into sphere centered on point
A. Movement of every point on this sphere (made by spiral) is same as rotations
of two directions (Rotations on circle and axis) explained in Double Sphere
