This is a Merkaba Metatron's Cube crystal grid made out of Birch wood. These are made to order, you can choose between approximately 3, 6, 9 and 12 inches in diameter and 1/4" thick. This is just for the grid, stones much be purchased separately.
Merkabah, also spelled Merkaba, is the divine light vehicle allegedly used by ascended masters to connect with and reach those in tune with the higher realms. "Mer" means Light. "Ka" means Spirit. "Ba" means Body.
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.
Crystal grid and healing sets are groups of stones that go together for a purpose. Sets of crystals and stones are used for ritual magickal or spiritual crystal healing purposes or with Reiki-Seichim energy work for healing. Some are generalized and others have specific purposes.
