RASHI :- Defined as per Vedic Astrology.

Before defining the RASHI let us know something about NAKSHATRA.

We have seen previously that there are 27 nakshatras and each one is of 13 Nakshatra degrees 20 minute's length by dividing the zodiac of 360 degrees by 27.

The Nakshatras are placed  3 in the SAVYA-MARG (i.e. upper half of the sine-curve) then 3 in the APASAVYA-MARG (i.e. negative half of the sine-curve) Again 3 in the SAVYA-MARG and so on.

One Naadi is allotted to one nakshatra.

SAVYA-MARG consits of 3 Nakshatras and so 3 Naadi's [ One Naadi is allotted to one nakshatra ]viz.

AADYA (STARTING, growing +ve side 60 deg of sine curve) ,

MADHYA (MIDDLE, peak  +ve side 60 to 120 deg of  sine curve),

ANTYA (LAST, +ve side 120 to 180 deg of sine curve).

APASAVYA-MARG consits of 3 Nakshatras and so 3 Naadi's [ One Naadi is allotted to one nakshatra ] viz.

ANTYA (LAST, -ve side 180 to 240 deg of sine curve),

MADHYA (MIDDLE, peak  -ve side 240 to 300 deg of  sine curve),

AADYA (STARTING, growing -ve side 300 deg to 360 [or say 0] of sine curve) .

1,2 3,   7,8 9 ,  13,14,15,   19,20,21,    25,26,27 are in SAVYA- MARG

4,5,6,   10,11,12,   16,17,18,   22,23,24 are in APASAVYA-MARG

EACH  NAKSHATRA  IS DEVIDED IN 4 EQUAL PARTS, EACH ONE IS CALLED AS CHARANA.

1 CHARANA = 3 degrees and 20 minutes.[3 degrees,20 minutes * 4 = 13 degrees and 20 minutes]

So there are 3*4= 12 charans in SAVYA-MARG  and 3*4=12 charans in APASAVYA-MARG.

A CHARAN IS CALLED AS RASHI
