The Biorhythm-Pyramid

To better illustrate the relationships between the various biorhythms, we can make use of mathematics and the Platonic solids already known to the Greeks. Platonic solids are mathematically expressed, polyhedra with the greatest possible symmetry. The tetrahedron is the simplest of the five Platonic solids. It consists of an equilateral triangle as a base and equilateral triangles standing on it. A tetrahedron is just like a regular pyramid, like the known buildings of the Egyptians. However, its base is square.

If you assign the 4 primary biorhythms to the 4 corners of a tetrahedron, then the connecting lines of the 4 corners and thus the edges of the tetrahedron can be assigned to the secondary biorhythms as we know them. This results in the following picture of the biorhythm tetrahedron:

It is always difficult to show a spatial representation on a sheet of paper. Therefore we can use a trick. If we cut open the biorhythm tetrahedron at the upper point and simply fold down the 3 side faces, we get a so-called body mesh of the tetrahedron. This body net is very easy to grasp and with regard to the biorhythm it shows very well the interrelationships of all biorhythms.

It is immediately noticeable that the previous upper point of the tetrahedron (intuitively) is now present 3 times, which was created by unfolding the biorhythm tetrahedron. The central triangle corresponds to the base of the biorhythm tetrahedron and shows us the basis starting from the primary biorhythms physically, emotionally and intellectually. The mathematical connection of 2 of these biorhythms corresponds to the connecting lines (sides of the triangle) and represents the respective secondary biorhythms. The same consideration is now applied to the mathematical connection of the 3 primary biorhythms with the 4th, the intuitive biorhythm. This results in the depicted outer triangle with its associated secondary biorhythms success, perception and mentality.

There are 3 more additional biorhythms that have been added in the course of development. These are the spiritual rhythm with a period of 53 days, the biorhythm self-consciousness (48 days) and the biorhythm aesthetics (43 days). The assignment of these biorhythms to the primary and secondary biorhythms was not possible until now.

However, the observation via the tetrahedron shows a possible connection. If we look at the periods of the 4 primary biorhythms in the tetrahedron, we can construct a connection in each outer triangle. In the triangle emotional (28), intellectual (33), and intuitive (38), the mathematical result is the arithmetic series 28-33-38. Continuing this series 28-33-38 automatically brings us to period 43, which corresponds to the aesthetic biorhythm. In the triangle physical (23), intellectual (33) and intuitive (38), one can continue the series 23-33-38 with 48, which brings us to the biorhythm self-consciousness with a period of 48 days. In the triangle physical (23), emotional (28) and intuitive (38), we can continue the series 23-28-38 with 53 (geometric series 23+5=28 + 10=38 +15=53) , which amazingly leads us directly to the spiritual biorhythm.

Summarizing a closed picture of the dependencies of all biorhythms and shows that the tetrahedron and the triad present in it can reflect our state of mind very well.
