Astrology is a divine science which correlates astronomical movements
of planets with physical, psychic and atmik/ soul's responses. this
science based on basic assumptions that planets do influence us, that
law of karma and theory of cause and effect is genuine and there is
continuity of life even after physical death.It is a science of the
influence of the planets and stars on human and terrestrial affairs.
The planetary motions and their positions and time(kaal)do have effects
on us. with the regular movements of planets one can fortell the
destinies of men,fates of nation, sudden inundations, earthquakes,
volcanic eruptions and other incidents relating to terrestial
phenomenon.
Vedic astrology is based on following five factores:
1. The planets- In astrology five planets mercury, venus,mars,jupitor,
saturn revolve in elliptical orbits around the sun. In astrology uranus
,neptune and pluto find no place.But the moon and the two shadaowy
points known as rahu and ketu, which are the moon's nodes are
equivalent to planets. They are not physical bodies but are
mathematically calculated sensitive points of intersection of the
orbits of the sun and moon.
2. Zodiac- the zodiac is divided into twelve equal partsof 30 degrees
each which are called the rashis of the zodiac. These are namely aries, taurus, gemini, cancer, leo, virgo, libra, scorpio, sagittarius, capricorn, aquarius and pisces.
3. Stars or nakshatras- The entire zodiac has been divided into 27
equal parts of 13 degrees and 20minutes each known as nakshatra
or asterism or a constellation. Every constellation has been
assigned a planetary ruler. Ketu is the ruler of the 1st
constellation starting from 0 degree aries and then the rulership
of venus, sun, moon, mars, rahu,jupitor, saturn and mercury follows
in this sequence till the end of the sign cancer. the same sequence
starts with leo.
4. lagna- in agtrology, the 1st house starts from lagnapoint. The
lagna or the ascendent is the rising sign in the eastern horizon
at a particuler epoch. The is dependent on the rotation of the earth
on its axis and so it is dependent on the sidereal time of a place
at a given moment or epoch. It is the point of intersection of the
ecliptic at a given time with the horizon of a place.
5. The houses- There are 12 houses. The sign where the lagna falls
is known as the 1st house or lagna. The next sign is second house,
next the third and so on. Zodiac is constantly moving and all the
12 signs get en opportunity to become lagna in 24 hours comprising
a day.
