Metatron's Cube is the only image that contains all 5 Platonic solids.
Platonic solids are a collection of all regular polyhedra, three-dimensional (three-dimensional) bodies bounded by equal regular polygons. With all the infinite variety of regular polygons (two-dimensional geometric shapes)
There are only five volumetric P. t., in accordance with which, since the time of Plato, five elements of the universe have been put: tetrahedron, cube, octahedron, icosahedron, dodecahedron.
Knowledge about the primary elements was available to ancient oriental cultures such as Indian and Chinese. Plato, as well as the Pythagoreans, thoroughly studied the philosophical, mathematical, and magical aspects of regular convex polyhedra. According to ancient knowledge, each of these polyhedrons corresponds to a certain element of the universe (primary element) and concentrates its energy. The vertices of the polyhedra radiate energy, while the centers of the faces absorb it.
1) Tetrahedron - fire. It has 4 vertices and 4 faces, resulting in the "Yin-Yang" equality.
2) Cube (hexahedron) - earth. It has 8 points-vertices emitting energy and 6 faces where energy is absorbed. Since there are more radiating points than absorbing points, then, in accordance with the Chinese teaching "U-Sing", the cube refers to the male principle "Yang".
3) Octahedron - air. The octahedron has 6 radiation vertices and 8 absorption faces. Therefore, the octahedron absorbs more energy than it emits, so it belongs to the feminine "Yin".
4) Icosahedron - water. The icosahedron has 12 vertices and 20 faces that look like regular triangles, so it expresses the principle of "Yin".
5) Dodecahedron-ether, prana. The dodecahedron has 20 vertices and 12 faces and therefore it expresses the Yang principle. Its 12 faces are shaped like regular pentagons.
