Merkaba is the electro-magnetic field that surrounds the physical body. It is entirely geometric, following the pattern of geometry found in the creation of living things. The shape follows the intersecting triangles found in the Christ Consciousness Series, but is third dimensional and when activated spins counter clockwise.
There are references to Merkaba (also called Diamond Body, Deva Deha, Siddha Deha, Star Body, Rainbow Body and Golden Pearl) in every religion and metaphysical philosophy. This includes Gnostic Christianity, the Old Testament, The Jewish Religion, the Rig Veda of Hinduism and Ancient Egypt.
The word Merkaba comes from Egypt. Mer means rotating light, Ka means Spirit and Ba means human body. Our soul is the divine spark of Source that manifests into and through our physical body. Merkaba, when activated and spinning, becomes the mechanism of Light Body creation, and is the travel vehicle that enables us to ascend (or descend) as the case may be, to other dimensions of reality.
An activated Merkaba is the end result of the alchemy of individual transformation and, ultimately, the Science of God Realization. Then our soul's spirit is finally released from ego, bodily identification and from the material experience.
