Star of David
The Star Tetrahedron is also known as the Star of David. The Star of David is the symbol of Judaism, a set of religious beliefs and practices that originated from the Hebrew Bible. It is interesting to note that, when drawn on top of one another, the 24 letters in the ancient language of Hebrew together form the Star Tetrahedron.
The most common arrangement of the Water molecule is in the geometric shape of the Tetrahedron. The molecule of Silicon is also in this geometric shape and, although it is currently Water that gives us life, Silicon can also support life. But what is most interesting is that the Star Tetrahedron is the geometric shape of a Silicon micro-computer chip. As we move toward 2012, the molecules of our cells are being alchemically shifted into those of multi-dimensional Silicon.
The Star Tetrahedron is the electric balance to magnetism. This is how data is stored so efficiently within a computer. It is this geometric shape that provides for memory. And the word memory takes its origins from the ancient Hebrew words mem, which means Water and ohr, which means Spirit.
No one can enter the kingdom of God unless he is born of Water and the Spirit….
You must be born again. John 3:5-7
The Star Tetrahedron has also been known since ancient times as the ‘Mer-Ka-Ba’ (Merkaba), the divine light vehicle (light body) 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; the two tetrahedrons rotating in opposite directions) which transports spirit/body from one dimension to another, as in the process of ‘ascension’.
What actually is the Mer-Ka-Ba? Technically, it is an electro-magnetic field that is geometric in nature. The Mer-Ka-Ba field is extremely complex, involving the five Platonic solids and other sacred polyhedrons. It is believed to extend through all possible dimensional and parallel universes, and can possibly change its nature from electro-magnetic to whatever is appropriate.
One of the functions of the Mer-Ka-Ba is to act as the vehicle to take the spirit and the body into the next world. However, this function - and most of the other possibilities - is impossible to obtain until something changes within the person. The Mer-Ka-Ba is situated around the human body like a three-dimensional geometric web that is dormant and non-functional, waiting for the right moment. When the spirit that inhabits the body remembers that it is there and begins to change certain aspects of itself, an incredible transformation begins to occur.
