In the present article I have chosen the topic Marriage Sanjog (Co-Incidence) as per the Horoscope chart in astrology. Here Sanjog means marriage yoga co-incidence. It is said that God almighty fix the marriages in the heaven. That's why sometimes girls & boys lives at the distant places but anyhow they come into contact with each other and get married.
Every girl & boy eager to know about her/his life partner before marriage. This curiosity take them to Astrologers. An astrologer with the sound knowledge of astrology can easily give the full details of their future life partner. After analyzing their birth chart (Kundali) he will easily tell the direction to which their life partner belongs.
Marriage Yog as per the Horoscope (Kundali)
Let us see the different type of marriage yog as per the astrological calculations. First of all let's talk about the Ascendant. It is not essential that bride & groom shall have the same ascendant in their horoscope chart. For example, one may have in his/her horoscope chart Aries Ascendant & the other may have the Scorpio Ascendant
In this picture boy has the Aries Ascendant in his horoscope birth chart.

In this picture girl has the Scorpio Ascendant in her horoscope birth chart.

The number in the chart denotes the number of zodiac.

I would like to make it clear to my esteemed reader that there are sixteen types of birth chart for different purpose. Navmansh Kundli tells about the life partner of the native of the horoscope.
Suppose one planet placed in the seventh house of horoscope chart of girl then it is quite possible that the same planet will be in the ascendant or in the navmansh ascendant of the horoscope of boy to whom she is going to get married.

One important thing is necessary to note that Venus in the horoscope birth chart of boy tells about his life partner. While Jupiter in the horoscope birth chart of girl tells about her life partner. For example1: If Venus sat in the first house of boy's horoscope and in the first house of girl's horoscope chart also, then marriage yog is possible between them.
Example2: The horoscope (Kundali) of boy or girl match with the navmansh chart of girl or boy, then also marriage yog is possible between them.
An astrologer while matching the horoscope birth chart of boy and girl, gives the match making number for compatibility in both the horoscope birth chart. As per the astrology there are maximum 36 number & there must be 18-20 or more than 20 match making number for a successful marriage.
