Metatron's cube contains every shape that exists in the universe God has created, and those shapes are the building blocks of all physical matter. They are known as Platonic solids because the philosopher Plato linked them to the spirit world of heaven and the physical elements on Earth. Those three-dimensional shapes appear throughout creation, in all everything from crystals to human DNA.
The Seed of Life is part of a group of shapes categorized as part of Sacred Geometry. Those shapes are - the circle, Vesica Pisces, Flower of Life, Fruit of Life and Metatron's Cube. Through its connection to these symbols, the seed of life is also related to the Platonic solids.
