ASCENDANT ( RISING POINT AT THE EAST ).
Raising point at the East horizon is
called 'LAGNA' or 'ASCENDANT'.
The point at which ecliptic rises
from the eastern horizon that determines the
first house in the horoscope. Find out
in which charan of which nakshatra is that point rising at the east. According
to the vedicRashi chapter determine the vedicRashi of that point. That
rashi number is written in the first house of the horoscope.
Previously we have seen that there is a
big question of measuring a circle. From which point we should start measuring
In the western system they measure the
longitude of the point from the vernal equinox i.e. the
point at which the sun crosses towards the north. That point is not fixed for
each year because it recedes with respect to stars. This phenomina is called
We, in India, measure the longitude of
that point from the star in the chitra nakshatra named SPICA (ALFA VERGINALIS)
+180 degrees. That point is the starting point of the Ashwini Nakshatra.
The difference between these two points is called as Ayanansh.
So if you use ephemeris as per the
western system then subtract the Ayanansh from the position of the planets you
will get the Nirayan position. USE ALWAYS THE NIRAYAN
For calculating which
point is rising at the east, at the given time and at the given place, the
Local Siderial Time is used. For that you can refer any astronomical Books.
Now find the Nakshatra and the charan of
that Nakshatra where this point is and find the RASHI of that Nakshatra-Charan.
That Rashi is the Lagna-Rashi.
