The 9-pointed Star signifies the ninth Sephiroth of the Qabala - Yesod, and its Astral energy where dreams and thoughts form into what will eventually be brought into manifestation.
The Triple Moons indicate water, feminine energy and the ebb and flow, waxing and waning nature inherent in all things. The lunar energy also resonates with Yesod and the Astral realm.
The three lines in the center are the glyph for the cardinal modality of Earth and represents the upward thrust of new growth. In addition to resembling the shape of a tree, the triple-line glyph also echoes other sets of Three: Maid, Mother, and Crone, Youth, Father, and Sage, triple deities, The Three Worlds, and the third Sephiroth, Binah - the first place of Form.
The downward pointing triangle is the alchemical symbol for Earth. Its silvery shape mirrors the shape of the Chalice and also the Cauldron of rebirth. It is the place from which we are born and to which we eventually return.
The spiral is a symbol of eternal life. It suggests growth, expansion, and positive cosmic energy as well as to be in harmony with the earth. The two spirals spinning infinitely inward and outward harken to our movement through and experiences of life, death, and rebirth. The whorls symbolize the continuous creation and destruction of the universe and all it contains. The spiral can also represent awareness of self, beginning at the core or center, and expanding outwardly, as the self develops, leading to rebirth and growth. The spiral shape reflects that which is found in nature, encouraging and allowing universal and earth energies to flow freely. The end points of the strokes of the spirals move energies into the chalice, pushed upward through Yesod by the glyph of cardinal earth and brought to the 32nd path of the Qabalistic Tree of Life and toward the manifest world.
The Golden square which encompasses all of the other parts of the sigil is representative of the Earth element, foundation, stability and the extremes of earth - sulphur and gold. It is the foundation of and vehicle for manifestation of our work and growth.
