De metafoor van de zeven lichtende centra

The word ekklesia, meaning an assembly, or group of people called together for some special purpose, a society, applies very neatly in the allegory to a nervous plexus, or ganglion, which consists of nucleated cells acting as a centre of nerve-force to the fibres connected with it. The seven Societies are the seven principal ganglia; later they are metamorphosed into "seven little lampstands," each ganglion being a little brain, a minor light-giver in the body, as the brain is the great light-giver, or microcosmic sun; and then they are changed almost directly into "seven seals" on a scroll, the chakras being indeed sealed in the materialistic person, so far as concerns their psychic functions.
