It is said that the Sun Sign tells us much about the individual spirit, and the Ascendant describes how others see us, the way we come across. The three most important personal areas in a chart are the positions and aspects of the Sun, the Moon and the Ascendant. The constellation of the planets and the zodiac signs they occupy shape very personal preferences and affinities that influence one’s perception, decision-making, and learning life lessons. The natal chart effectively is a snapshot of the planets and their positions at the moment of birth, the moment a baby draws its first breath.
