From a global point of view this diagram represents a square at the center of which is source energy ... a square is a symbol of the physical world. The 9 circles enclose knots of energy constantly emitting their specific forces in all directions, they act as portals into other dimensions. Expanding to a 3 dimensional model we obtain a cube with each of the 8 peripheral symbols on one of the corners, with again source energy occupying the center ... in short it is a symbolic representation of a physical structure capable of space/time travel into parallel universes.

As for the meanings of the symbols they are most probably a condensation of the 36 forces as enumerated by Felix Servranx in april 1949, the result of his research into the question " how many forces are there in existence? "

This list can probably be expanded or paralleled ... let's remember there are (2 x 36) 72 forces listed in the kabala.

Here is the list of forces as enumerated by Felix Servranx;

1-spiritual 2-life 3-thought 4-conscience 5-cosmic 6-ultra violet 7-vital magnetism 8-physical magnetism 9-light 10-radioactivity 11-vital static electricity 12-nuclear energy 13-sexual force 14-waveform 15-disintegration 16-vital evolution 17-sound 18-ultra sound 19-vital dynamic electricity 20-zodiacal(influencing life) 21-planetary(influencing the mental) 22-animal 23-nervous(and resonance with perfumes and aromas) 24-organic growing force 25-physical dynamic electricity 26-physical static electricity 27-vegetable 28-mechanical force 29-gravitation 30-hertzian waves 31-chemical affinities 32-dielectric 33-mineral 34-healing?(a force that seems to assist in repairing damaged tissue, in healing illness) 35-infra red 36-heat

have a great day ... bb2 :)

hi supergirl, come to think of it the answer to your question is in the phrase " from the inner being: through sight, sound, touch, and feeling are manifested the path, windows and doors to the unknown, which always leads back to the inner being"

the inner being is represented by the central dot and the four senses sight, sound, touch and feeling are represented by the four symbols forming a cross in the diagram ... as explained in the nine star key, source energy (chi) flows through all things, including our own bodies ... and expresses itself through water, fire, earth and air and travels along defined pathways ... these are all different states of the same energy and can be applied to any system ... the enneagrammatic circuit diagram represents a dynamic system of interacting energy states ... and as explained in the i ching book of changes these four basic states of energy are dual, they always have a counterpart ... in short the diagram indicates the inner being in the centre, and the eight other symbols represent sight, sound, touch and feeling and their dual counterparts ... have fun bb2 :)

Here are some interesting results ... using my pendulum i researched which symbols syntonized with which meanings; here is the list given by Stingray

1-eye 2-mouth 3-hand 4-water 5-path 6-window 7-door 8-the unknown

and here is what i found using my pendulum using the same order;

1-sight(counterpart) 2-sound 3-sound (counterpart) 4-feeling 5-feeling (counterpart) 6-touch 7-touch (counterpart) 8-sight (into the unknown?)

well worth meditating ... have fun :)

p.s. the symbol 6 indicated by stingray as being "window" corresponds to yod-he-vau-he (tetragramaton)

http://en.wikipedia.org/wiki/Tetragrammaton

used in the lower banishing ritual of the pentagram ... it is an effective shield against negativity.

9 dec update ;

The enneagrammatic circuit has the same structure as a 3 x 3 magic square which is a layout of an equal number of rows and columns containing the symbols 1 to 9 and each row, column and diagonal always adds up to 15

ffff

changing the value of just one symbol causes the other symbols to be readjusted accordingly so as to maintain a state of equilibrium ... the enneagrammatic circuit performs in a similar way, it's a self adjusting dynamic mechanism ... just like the loa ... in other words the enneagrammatic circuit is a diagrammatic representation of the loa applied to humans

have fun :)

The icosahedron, that is, a 20 sided polygon, when viewed by certain angles internally bears resemblance to the enneagram.

This implies that when we perform this exercise, we are inside the symbolic form a icosahedron, which can be compounded with the dodecahedron

http://en.wikipedia.org/wiki/Compound_of_dodecahedron_and_icosahedron

In other words symbolically we live inside a mathematical structure that can be graphically represented by the 12 sided polygon as so clearly shown in the servranx graphic no.37

Now lets take a closer look at the meanings of the symbols in the enneagrammatic circuit

ffff

As shown 1,2,3 correspond to physical aspects.

5,6,7 correspond to the non physical counterparts, the essential energy aspects.

4, water acts as the medium that allows communication.

8 corresponds to perception, the capacity to differentiate.

9 corresponds to a unified being in perfect health.
