What is Astrology?
Vedic Astrology is a scientific study and application of the language of the heavenly bodies (planets and stars). These heavenly bodies are determined on the basis of astronomy and mathematics, are mapped in the form of a horoscope. Their specific position in the horoscope indicates specific happenings in the case of individuals. The main factors affecting the horoscope of any individual are Date of birth, Place of birth and exact time of birth. Whether the sun, the moon, the planets and stars themselves influence the terrestrial phenomena, or they only indicate such phenomena by their various dispositions, is immaterial. What is important to us is that variation in their disposition determine variations in the events on the earth, the correlation are very strong.
In Hindu Astrology, this system has been explained as space time connection. Within the space, there are four elements Air, Fire, Water and Earth each is therefore attributes, sattva , Raja and Tamasa and make up 12 divisions in the nature. So the zodiac in which earth and all the planets are imprisoned by gravitation and revolve around the sun is divided by 12 clusters of stars or signs of the zodiac.
In Vedic astrology it is found that nothing in the universe is stationery. In any case we consider ourselves in the central point with rest of universe in the constant motion around us. We, therefore, consider the position and movement of all the heavenly bodies in relation to earth itself. The Indian Astronomy and Astrology considers earth as the centre, and all other heavenly bodies moving around it in one manner or the other.
