Why is it important to get horoscope match done before the marriage? The answer is simple our nature can be influenced by the kind of environment we live in. When two compatible people come together they certainly agree with many things that affect the life for good or bad but if two not so compatible people come together they might influence their surroundings for worse. Astrology does not advice any one against love marriage. Even if two incompatible people come together astrology will suggest a remedy on adjustments for blissful life ahead.
In many conservative societies Kundli matching is still considered as one of the most important ritual before the marriage. When a kundli analysis is done there are many factors which decide timing of ones marriage and nature of married life.
