Historical definition of Merkaba
Let Drunvalo Melchizedek, the author of The Ancient Secret of the Flower of Life, volumes I & II, answer:
“History has talked about the Mer-Ka-Ba mostly as the vehicle that allows a person to ascend or descend into the higher or lower worlds. But actually the Mer-Ka-Ba is much more than just a vehicle of ascension. It can be, really, anything — since it is the primal pattern that created all things and all universes, both visible and invisible (see The Ancient Secret of the Flower of Life, volumes I & II).
In the Bible there is reference to Ezekiel and the wheels by which Ezekiel ascended into heaven.[3] This was the Mer-ka-Ba.
In the Torah, there is reference to the Merkavah (as it is spelled in Hebrew) which has two different meanings: One meaning is ”chariot,” which is a vehicle; the other is the ”Throne of God.” When the two definitions are combined, the true meaning comes to life.
In Ancient Egypt, this primal pattern was called the Mer-Ka-Ba. It was actually three words, not one. Mer meant a kind of light that rotated within itself. Ka meant spirit, in this case referring to the human spirit. And Ba meant the human body — though it also could mean the concept of Reality that spirit holds. And so the entire word in ancient Egypt referred to a rotating light that would take the spirit and the body from one world into another.”
Description of the Merkaba
“What actually is the Mer-Ka-Ba? Technically, it is an electro-magnetic field sitting at about four degrees Kelvin, found primarily within the microwave range — at least in the third dimension — that is entirely geometric in nature. Specifically, the geometry used is called ”Sacred Geometry,” as this particular geometry is found in the creation patterns of all things in Creation.
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.
The blueprint of the Mer-Ka-Ba is found throughout nature, such as in this photo of a galaxy.”

Hologram activation of your Merkaba and how to program it
It is really simple to activate your Merkaba:
1°) Touch the picture of the hologram (open the pdf file);
2°) Think about your Merkaba around you;
3°) Visualize the sun
Once you Merkaba is activated, you can also program it. Here is how to proceed:
1°) Touch the Merkaba hologram;
2°) Think about the programmation.
That’s all !
Examples of programmation:
Protection from negative thoughts if not negative energies;
Quality you desire to develop in your life;
More energy in your body…
Merkabah around objects, houses, businesses…
You can also create Merkabas around everything that exists… and program them (see above).
Your imagination is the limit!
