Since ancient times, people have looked to the stars to gain wisdom and insight for the direction of their lives. In the fourth century B.C. in Babylon, astronomers passed along to the Greeks a system for understanding the signs of the cosmos as they related to human life. The twelve signs of the Zodiac name the position of the sun when a person enters into the world. Because the sun is the largest body in our solar system, the gravitational pull it has on a new being has the power to shape that person for life. 

Of course, as the sun shapes our personalities, it also shapes the personalities of all those we interact with and has a significant influence on the way we interact with each other. For these reasons, understanding which signs you're compatible with and — just as importantly — those you're not, can help you to make sense of the challenges you may face in relationships. 

Astrological compatibility does not predetermine whether a relationship will succeed or fail. It merely gives a way to understand where difficulties and pleasures may be coming from and provide insight into how a couple may best work through their differences and celebrate their confluences. Finding out that you’re not astrologically compatible with a partner does not mean you should say goodbye. It just gives you a guide for how to approach your differences.
