Indian astrology is the oldest wisdom
found even in Atharva Veda 3000 B.C. back. Indian astrology
is based on the relative positions of stars or planets
at the birth time. Mainly the nine planets are supposed
to influence the life of a person. These are Sun, Moon,
Mars, Mercury, Jupitor, Saturn and two shadow planets
Rahu and Katu.
To predict life events of a Person the relative positions
of these planets are determined and several charts and
Dashas Are made and calculated. There were several Rishies
who gave several systems to calculate & prepare
these charts and Dashas. Prominent names among them
are Parasher Rishi and Varahamihir and many others.
It is quite difficult, even to study a system thoroughly.
Astrology is widely used all over the world. People
use it in different forms according to region and culture
of the area.
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 founded 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 heavinely 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.
The Indian astronomy is thus geocentric, and not heliocentric
which latter considers sun as the centre.
