Two spheres that are same in size (Sphere A, sphere B centered on point
A, point B) are rowed, center of one sphere having contact with surface
of another sphere. Relationship for centers of both spheres to have in
contact with surface of another sphere is always satisfied. (Fig.9)
Suppose sphere A moves around sphere B in clockwise direction. Sphere A rotates on its axis the same degrees as degrees of movement around sphere B in anticlockwise direction.
Keeping this relationship, if sphere A moves around 360 degrees, every
point on sphere A, passing point B, moves in simple harmonic motion centered
on point B. (Amplitude corresponds to diameter of sphere.)
In this movement, only points on circle (Intersecting point of sphere
A and plane including axis passing both point A and point B) on sphere
A moves in simple harmonic motion centered on point B.
Point A needs to move around sphere B, rotating on axis passing both point A and point B, in order for every point on sphere A to move in simple harmonic motion centered on point B. In addition, rotation on axis is far slower than rotation of arrow in Fig.9. Suppose number of rotations of the former is infinite, while number of rotation of the latter is one. So, every point on sphere A moves in simple harmonic motion centered on point B.
As described above, by interaction of 2 spheres, movement of every point on sphere can be converted to simple harmonic motion. (Explanation described above can easily be understood by referring to explanation of double circle)
Movement of Double Circle is intersecting point of movement of Double
Sphere and plane (plane including both point A and point B). Movement is
limited on this plane in Double Circle, but this plane itself rotates in
Double Sphere.

As described above, it can be understood that conversion of movement of
rotation by Double Sphere Structure to simple harmonic motion is situation
for simple harmonic motion by Double Circle Structure to be rotated on
axis passing both point A and point B.
This situation agrees with recognition situation for us to recognize up
and down and left and right.
Recognition target (Matter) is sphere, consciousness (It moves back and
forward of matter) is expressed by simple harmonic motion.
The case in which sphere A moves around sphere B was explained, but it is possible for sphere A to be fixed. It is thought in this case that relative relationship of sphere A and sphere B is kept. So, every point on sphere B moves in simple harmonic motion centered on point A.
Addition of movements in simple harmonic motion centered on point A and
point B makes rotation component zero. (Please refer to explanation of
Double Circle). The reason why rotation can’t be felt is that rotation
components become zero.
As described above, it can be understood that Double Sphere Structure is basic structure of consciousness.
