Some form of astrology has probably been practised in all cultures since civilisation began.
Astrology is the study of the movement of the sun, moon and planets against the backdrop of the fixed stars which we call the zodiac, and the correspondence between this movement and events taking place on earth. For thousands of years, observations have been made of the way planetary cycles affect human behaviour.
The birth chart is quite literally a map of a particular moment and, like a picture on a packet of garden seeds, shows what we might become.
The horoscope is drawn giving the longitude position of the sun, moon and planets in relation to the signs of the zodiac at the exact moment of birth and their spatial position in a 12 house division, according to the place of birth.
Astrologers study both the fixed and the changing aspects of life. While the birth horoscope shows a snapshot for a given moment in time and is thus static, the planets are constantly moving around the zodiac, which gives a dynamic perspective. A consultation with an astrologer will involve a discussion with the client on the psychological patterns, talents and potentials indicated on the client's horoscope. Looking at the dynamic perspective (the current "transits") is useful at any time but particularly helpful when you feel at a crossroads in life and are not sure of your next direction.
