A Tetrahedron is a platonic solid made of 4 equilateral triangles forming a pyramid shape with angles of 60 degrees in other words a 3 sided pyramid. A double pyramidal tetrahedron is one tetra pointing up and the other pointing down with what looks like  a common base. It has been referred to as the template of physical reality, it has also been refereed to as a quark
 

I made a model of this shape in wood, implied the bottom tetra with wood, so that I could put  crystals on this model, the idea was that I could use it, put myself and others in it by hanging it on a planter pole and to be able to sit with my head in the center of the triangle that formed the base. After completing this model (before the crystals were applied) I noticed that the energetics  of this structure seemed to multiply, it seemed to be reproducing itself, I put my hand at each corner point and moved my hand to the center of the triangle and could feel that the energy stopped at the center, the energy sported in the center of each triangle. I therefore concluded that each equilateral triangle had a still point. Then I discovered that the equilateral triangle needed only be applied, in other words, you only need  an angle of 60degrees and the whole thing will begin to multiply and become more. Even if the angle is only an implied angle it will still multiply
At the time this model was made I did a meditation, where I was given a meditation to use with this model.
The meditation was as simple as in your imagination to step into the double tetrahedron with who you are now, then step out f it, imagine any changes you might want in your overall picture of reality, know  that at this point that this is you and step back into the shape

A group of people came to my home and we did some experimenting with this model. We had a whole pile of ginny pigs and a person with a device that could measure our energy fields. She said that she didn't expect any effects to alter anything and if there were any effects that they would probably dissipate within 20min.
So we began - each person tried sitting within the model, after just sitting in it our energy fields were changed, using the meditation I had been given while sitting in it raised the energy fields even more, we were monitored before - during and after our little experiment, what was interesting was that the energy did not dissipate but continued to rise.

Discovered in meditation as I 'saw' this in my body and seemed to be aware of certain things:
Now I have discovered that the double tetrahedron or quark, is in constant movement, it not only reproduces itself but it moves through itself from base on base to tip on tip. The one tetrahedra which has multiplied itself also moves through itself and spins and rotates at the same time. The geometry that we see is only a snap shot of a slowed down version of this self perpetuating energy. The snapshot of when it is in the double tetrahedron position is acting in the mode of 3D reality as in the idea of the template, it is the vibration at that point as it moves through itself. It is the holographic snapshot that is viewed when any aspect of that is seen. For instance the MerKaBa is a snapshot.
In my opinion the platonic solid called tetrahedron will fit into all other platonic solids, ie. cube.
