The Planetary Merkaba is a sphere defined by 6 intersecting rings.
The geometries of this sphere are defined by a Star Tetrahedron.
The Star Tetrahedron has 8 outer points and there are 6 X's formed when the 2 Tetrahedrons are combined.
Where the Star Tetrahedron points touch the outside of the Planetary Merkaba Sphere, 3 rings cross at those 8 points.
Where the 6 X's are on the Star Tetrahedron, 2 rings cross above those 6 X's.
This version of the Planetary Merkaba Sphere does not include the inner Star Tetrahedron.
Also available with a Simple Star Tetrahedron inside
and with a Flower of Life Star Tetrahedron inside
