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, 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.
Mahendra Porutham is drawn, based on the birth stars of the couple and denotes longevity, progeny and wealth. It also signifies the man’s capability to protect his wife and children in terms of finance, moral support and protection from the evil forces of the world. It is widely believed that presence of Mahendra Porutham between the couple is sufficient in the absence of Dina Porutham and Rasiyathipathy Porutham. Mahendra Porutham is considered ‘Uttamam’ (compatible or good) when the boy’s birth star is in the positions 4th, 7th, 10th, 13th, 16th, 19th, 22nd and 25th from that of the girl’s birth star. The other positions are considered incompatible and not taken into account for marriage alliance.
