The 13 spheres represent an extremely powerful sacred geometric pattern known as the Fruit of Life, considered the Holy of Holies of Sacred Geometry because it’s hidden within the ancient and well-known Flower of Life pattern.
The fruit of life is composed of 13 spheres; this is actually the 2d representation of a 3d structure Thirteen represents unity and transition between worlds / dimensions.
Those of you who play an instrument know the chromatic scale of 12 notes the thirteenth note is actually repeating the first note but on a higher frequency; when you attain a higher octave you enter a higher dimension. If we connect all the Centers of the 13 circles the result is 78 lines which create a structure known as Metatron’s Cube. This structure contains all five platonic solids, these three-dimensional figures and their different combinations reveal every possible geometric law forming the physical reality we are experiencing.
The spheres of the Fruit of Life represents the female movements or elements of creation and provide the field for the 78 ray like male movements of creation. The geometry of Metatron’s Cube is set to underlie what modern physics calls the quantum vacuum or void and is fundamental to the creation process at the quantum level. What we’re talking about here is what’s been called zero-point, life force or bio force energy.
