I have Antares, Eros and Mercury all conjunct in Sagittarius 5th.Antares is is one of the four royal stars of Persia, in the ancient times...
I find to understand Antares, is helps to understand the nature of Alderban.
Alderberan is like, the cultral buddha, it wants to keep everyone safe in society, to inform of the knowledge, and to govern the people, with no lies or secrets, it wants to remain calm and be steadfast and courageous in direction.
Antares on the otherhand, want to fight for evolution, it is the people of anarchy, saying "Fight the power", it tells people we need change, and we need to do it ourselves by being headstrong and determined, it would rather kill itself than be ruled by a goverment that doesn't serve the evolutionary needs of the people..
Hope this helps
