In modern esoteric teachings, it is taught that the MerKaBa is an interdimensional vehicle consisting of two equally sized, interlocked tetrahedra of light with a common center, where one tetrahedron points up and the other down. This point symmetric form is called a stella octangula or stellated octahedron which can also be obtained by extending the faces of a regular octahedron until they intersect again.
Merkaba, also spelled Merkabah, 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. Mer-Ka-Ba means the spirit/body surrounded by counter-rotating fields of light, (wheels within wheels), spirals of energy as in DNA, which transports spirit/body from one dimension to another.
