The 12 Rashis (Moon and Rising Signs)
Each Vedic sign explained: ruling planet, element and nature, the planets exalted or debilitated there, the Nakshatras inside it, and Rasi Porutham with every other sign.
Moon sign, rising sign and Sun sign
In Indian astrology the Rashi usually means the Moon sign, the sign the Moon occupied at birth, and it is the sign used for daily horoscopes, Sade Sati and marriage matching. The rising sign (Lagna) describes body and temperament, and the Sun sign describes purpose. All three can be different, and the sidereal zodiac used here usually places them one sign earlier than Western astrology.
Using {sign} in matching and timing
Rasi Porutham compares the two Moon signs in a match by counting from one to the other; some counts are considered harmonious and others need care. Saturn's transit over the sign before, over and after {sign} forms Sade Sati for people with this Moon sign. The compatibility table on this page links to a detailed page for every pairing.
