The Sun blazed in dynamic Aries, a fire sign on your birthday. The Sun in astrology stands for your inner nature, the light of your essential character. Aries, the first sign of the Zodiac, is a masculine sign ruled by the warrior planet Mars, whose motto must be "Crash through, or crash!" A cardinal (creative and inventive) sign, Aries, the Ram, governs leadership and initiative. Aries people are bold and self-confident, although they tend to be overly impulsive.
