In decoding the cryptic symbolism of an astrological chart there are four aspects that need to be taken into consideration: planets, signs (zodiac), houses, and aspects.
Planets can be thought of as energetic bodies where ideas and archetypes exist. The zodiac signs show us how these influences operate on the micro and macro levels; in short the character and style in which they reveal themselves. Houses show us where these influences operate as in the environment and circumstance the ideas surface. Aspects are the flow of force between the planets showing us the use and abuse of these energies operating your magnetic field.
