Marriage is a special and life-long bonding between a man and a woman. To ensure a happy and contented married life, our ancient system of horoscope matching offers great help in studying the compatibility between the boy and the girl contemplating for marriage. In this system, the horoscopes or birth charts of the boy and the girl are drawn based on their birth stars and moon signs to analyze the compatibility of their natal charts for a happy married life. For this reason, our ancient sages have penned down twenty Kootas or Poruthams (compatibility factors) to be studied during horoscope matching or kundali matching, of which only ten Poruthams are considered more important in present day. In some parts of India, only eight Kootas are considered for marriage. The twenty seven nakshatras or birth stars are arranged in an oval shape in the sky which constitutes the zodiac system. The zodiac transits around the nine planets, thus influencing the nature, life events and physical and mental attributes of individuals on Earth. Hence, it is very important to analyze the compatibility factors (Poruthams) of both the boy and the girl deciding to enter into married life.
