This configuration goes by many names due to its historic use and geometric shape: Solomon’s Seal, star tetrahedron, diamond tetrahedron, and more generically described as a ‘hexagram’ or six-sided figure. It is also called a ‘Grand Sextile’ in astrology. Some have even referred to this special configuration as the “MerKaBa,” or gate. Any of these key terms you can google and find oodles of information from all different sources. Take your pick.
Now regarding the SOD configuration’s astrological meaning, I’ve been aware of different astrologers’ opinions regarding this configuration. Many are ‘playing it up’ in importance (because it is so unique that it must signify something) but without a lot written on what the configuration portends other than the historically surmised “birth of a king,” you are unlikely to find a standard astrology-by-book interpretation.
Perhaps even more intriguing, is that many astrologers are glossing over SOD, merely mentioning it with no real emphasis. For instance, the astrologer Susan Miller feels that there’s a missing moon phase to kick this massive energetic aspect into gear. You can see her website at astrologyzone.com. I partly agree with her. Though this configuration may come and go with some silence on the subject, it is certainly not due to lack of its power.
What will it mean? I cannot honestly say what it will mean, on a personal level, nor for identities such as countries, nor for what it means to the global community. But, I will say that I feel it to be a “dawning.” SOD in the sky is like a stamp of unknown official meaning. Do what you will with it. In fact, it is like a gateway of truly palpable and powerful energy that orders itself like a lock and key (perfect fit), and just commands the beginning of a new era. What is commanded?
SOD symbolism is ancient – that’s for sure – and it’s potentially even more ancient than its use by the Hebrews whose 22- character alphabet is said to be actually hidden within the star ( Magen David or Shield of David. The Star has been used in the sacred geometry of matter, with its meaning in alchemy as the joining of Fire (upward facing triangle) and Water (downward facing triangle). In the Indian tradition, SOD represents the Sat-Kona, or Lord Krishna’s abode, referred to as the Star of Goloka. Tantra has even claimed some meaning of the SOD as a sacred yantra representing the merging of Shiva and Shakti, the divine masculine and feminine principles in the universe. Wow. That’s some meeting!
Perhaps this Star of David configuration best reminds us that the universe is so complex and permutable, and our experience of it is more than just the fluctuation of dualities (good and bad aspects), but a meaningfully woven experience with a central purpose and sacred harmony. ‘Be Still and Know that I AM God.’ Our experiences on earth are processes by which we refine our soul and polish our mirror. This seal is about the light of the soul, its ability to stay on the path, guided by inner stillness and openness to All that Is. The triangle of water is represented with Saturn in Scorpio, Mars and Jupiter in Cancer, and Neptune in Pisces. The triangle of earth is represented by Venus in Virgo, Moon in Taurus, and Pluto in Capricorn.

I have read a little about the tantric symbolism of the Star of David. From what I’ve heard the triangle that is broad at the top represents the masculine principle and the one that is broad at the bottom represents the feminine principle. Like the shapes of male and female bodies, respectively.
Here is an interesting website with glyphs from Barbara Walker’s: The I Ching of the Goddess. http://unurthed.com/2010/09/30/the-double-triadic-hexagram/
“The original triangle stood for the Goddess’s trinity of Creator, Preserver, and Destroyer, she of a thousand names, such as Maya the birth-giving Virgin, Durga the preserving Mother, and Kali Ma the death-dealing Crone. Her primary symbol was a downward-pointing triangle, the Yoni Yantra, sometimes called Kali Yantra. This represented a vulva (Sanskrit yoni), and femaleness in general: by extension, a womb, motherhood, female sexuality, the life spirit embodied in menstrual blood, or the world-activating power of the Goddess herself. The same symbol stood for ‘woman’ and ‘Goddess’ among ancient Egyptians, pre-Hellenic Greeks, Tantric Buddhists, and the gypsies who migrated westward from Hindustan. The primordial female triangle became a male-female hexagram by eight stages, graphically represented as follows.”
Thanks for those links. They really helped clarify.
