Astrology: The most basic aspect of astrology, star signs or sun signs has been popularised in horoscopes that appear in daily newspaper columns and magazines.
Astrology is about the interaction between the Planets (including the Sun and Moon) and the Signs. The relationships between them and their interactions are mathematically based, and Astrology studies these mathematical cycles. Each Sign represents a different aspect of the whole human.
Aries starts the cycle, representing the Self, and Pisces completes it, representing the mass unconscious of all mankind. In between, each other Sign carries the energy of a different phase of man's evolution within the universe.
Your sun sign/star sign represents the Sign of the Zodiac that the Sun was in at the time of your birth. The Sun rules will power and ego. It is the core of your potential and uniqueness as an individual; who you are and what you are about. The forces between the Planets involved in Astrology can be simplified into one word: gravity. The Sun has the greatest gravity and the strongest effect in Astrology.
