The horoscopes of the bride and groom are compared during Kundli matching to determine if their married life will be happy and prosperous. If 18 or more points match, it is a good marriage; if the points match less than 18, the marriage is not authorized by astrology. However, many consider any match beyond 20 as a good sign. In addition to its religious significance, kundli matching is also used as a tool for successful marriage prospects. The couples' birth charts are taken at the time of registration of marriage with the help of modern tools like computer software. Based on this analysis, an expert in astrology can predict whether the marriage will be successful or not. If you are looking for something similar to kundli matching but based on Indian astronomy rather than European then this is called natal chart matching. Two natal charts are drawn independently for the bride and groom and the similarities between them are noted. Based on these observations, some experts in India can predict if the marriage will be successful or not. There is no scientific evidence that supports using kundli matching to find a partner. However, it is still practiced by some people. In conclusion, kundli matching is based on the belief that happiness in marriage depends on how well the stars align. This practice has been around for many years and has no scientific basis.
