Learn the complete meaning of the 12 zodiac signs in Tamil astrology. Understand their personality traits, nature, life path, family life, career possibilities, and their importance in astrology explained in simple English.
What is Raasi?
Raasi is one of the most important concepts in astrology. A Raasi refers to one of the twelve divisions of the sky in the zodiac. The Sun travels through these twelve sections during the period of one year. These sections are known as the 12 Raasis or zodiac signs.
In astrology, the Raasi in which the Moon is positioned at the exact time of a person’s birth is called the Janma Raasi (birth sign) of that individual. Because of this, astrologers study a person’s Raasi to understand their character, life path, personality, and many other aspects of life.


Things That Can Be Known Through Raasi
According to astrology, many aspects of a person’s life can be understood through their Raasi. By studying the Raasi, astrologers can explain the following:
- A person’s character and nature
- Life approach and behavior
- Family life and relationships
- Career and personal growth
- Health and wellbeing
- Marriage compatibility
In Tamil astrology, both the Nakshatra (star) and Raasi (zodiac sign) are considered very important when checking marriage compatibility (Thirumana Porutham).

Questions About the 12 Raasis
Below are simple answers to common questions about the 12 Raasis, Janma Raasi, Raasi compatibility, and the importance of Raasi in astrology.
1. What is Raasi?
Raasi is an important part of astrology. The zodiac sign in which the Moon is placed at the time of a person’s birth is called the Janma Raasi or birth sign. Through this Raasi, astrologers try to understand the person’s character, thinking style, life approach, and certain astrological meanings. In Tamil astrology, Raasi, Nakshatra, and planetary positions are usually studied together.

Astrology says that each Raasi has its own nature, qualities, ruling planet, and life-related meanings. Because of this, every Raasi is seen as having its own special importance.
3. Why is Raasi important in marriage compatibility?
In Tamil astrology, Raasi is considered an important factor when checking marriage compatibility. By comparing the Raasis of the man and woman, astrologers explain things such as mindset, family peace, compatible life, and relationship stability. However, Raasi alone is not enough. It is better to also check Nakshatra compatibility, horoscope structure, planetary positions, and other matching factors.
4. Are Janma Raasi and Nakshatra the same?
No, Janma Raasi and Nakshatra are not the same. The Raasi where the Moon is placed at the time of birth is called the Janma Raasi. At the same time, the specific star where the Moon is placed is called the Janma Nakshatra. In Tamil astrology, both are important. Raasi helps explain many parts of life, while Nakshatra gives more detailed astrological information.
5. What can be understood through Raasi?
Through Raasi, astrology explains a person’s general character, thinking pattern, family affection, career direction, mental nature, and life approach. Some people also use Raasi to check marriage compatibility, planetary effects, and daily horoscope results. But for a complete astrological understanding, Raasi alone is not enough. Nakshatra, Lagna, and planetary positions should also be studied together.
