Below is a chart showing the generation of the next level of spheres, after the Vesica Pisces, which has its basis in the seven days of creation, and ultimately forms 13 spheres which is known as Metatron's Cube.

The graphic below is taken from "Sedona. Beyond the Vortex" by Richard Dannelly.

Within these spheres is the potential for the generation of the building blocks of creation known as the Platonic solids.

Around each of us is an electromagnetic field of energy which is our consciousness. Most of us feel that our consciousness is created within our physical brains. This is not the case. Our physical brains are just the vehicle for the reception of consciousness into this incarnation, into this reality.

We also exist on many levels of consciousness. These levels of consciousness, or dimensions, correspond to the musical scales within an octave. At the moment, humanity is focussed, in incarnation, on the 3rd plane of consciousness. We are working collectively, on the 4th level consciousness, and are evolving to the 5th level of consciousness. The magnetic structure of each of our electromagnetic energybodies, on each of these levels of consciousness, corresponds to one of the Platonic Solids. This electromagnetic energy field around each of our dimensional bodies is the Merkabah Lightbody for that level of consciousness.
