Glass; like the human body is made up of spherical parts; that allow light; or photon particles, to pass thru in two ways; first, it is refracted and focused by the spherical; or lensing spheres; and second; it can pass thru the spaces left between the spheres.
To witness the sphere to sphere focusing effect; you can simply look at a rainbow; or stand on the bow of a ship at night; and watch the bubbles transmit the star light into the bow wave of the moving ship; as it forces its way thru the water.

So it doesn’t take a lot of imagination to see and know that the sun light striking your body on a sunny day; is also penetrating and being focused into the interior of your body.Those spherical lensing cells are taking the white light and refracting it into your body as a rainbow of colors.
Consider standing under a tree; there are spots of light on the ground where the leaves allowed light to reach all the way to the ground; uninterrupted and delivering full strength to the ground. That can be compared to the cells of the body; or the spherical glass lenses; which have spaces in between the spheres; which allows for uninterrupted penetration of the photons of light when entering the body or passing thru a convergent lens.

I have read that as much as twenty seven percent of the Earth is silica. Which is the primary component of quartz. Glass is silica in one form; and according to the ancient view; the doctrine of the micro-cosm and the macro-cosm; the Earth and the human body are percentage wise; one and the same as far as percentages of composition are concerned. Considering, now, the brain specifically; it has been said to be a liquid crystalline mass. Cells are lenses; lenses focus light and transmit light from cell to cell to cell. Not only do they transmit but being convergent lenses; they focus light into the focal spear of the various spectral colors; as a spear or sword of light.

Unlike a laser; the convergent lens focuses all of the spectral colors; and coordinates their spins into a harmonious progression in which we see a rainbow array with no photon particles or gaps between the colors. Both the gaps and the photon particles are eliminated from view; by the bow wave of the particles. It’s amazing that the photon particles can go thru glass; passing thru between the atoms which being spherical not crystalline; they allow the photons to go thru a window; or a convergent lens; even when being refracted to a focal point; as is the case with the convergent lens.

There is an important difference that should be considered between the glass spheres and the cells of the human body. The glass spheres are unchanged during the passage of the photons. While the cells being liquidic lenses are set into revolution by the vortexial motion of the spin; or gravitation of the motion of the photons. That motion of gravitation is the origin and cause of the attraction; and generation of bi-polar motion and life.
