Sphere - Medium
Spheres enfold everything within them, symbolize completion, and are like gateways to new realms. Spheres encompass realms that have been incarnated, like souls that are reincarnated in bodies, and thus in this sense spheres have a bodily dimension.
Spheres also symbolize worlds and planets. In conjunction with tachyons, spheres help us to let go and to come back down to earth.
