This is the first transiting Star of David that I was aware of. I think that each of the Stars of David that appears in the sky tell us something about the human experience and spiritual journey as it is occurring on the planet, both individually and connectively. It is interesting to note what happens during the time periods of each of the Stars. On August 2, 1990, Iraq invaded Kuwait and many countries rallied together, considering the invasion an injustice. The Gulf War began. The 1990 Star was a War Star as noted by the Mars in Taurus tightly square to the Sun in Leo. Both are part of a T-square with Pluto in Scorpio.
This Star of David was a earth-water Star and called for material manifestation (earth signs) and cleansing (water signs). Iraq invaded Kuwait over an oil dispute and slant drilling. Water and earth create mud as we know. But besides being dirty, mud can be dried to create bricks, a building material. The Berlin Wall was coming down during this time and the reunification of East and West Germany occurred on October 3, 1990. The Soviet Union was collapsing, civil war was beginning to break out in Yugoslavia, and the marriage of Princess Diana and Prince Charles was failing.
