In Vedic astrology, the first step to analyze marital harmony between two people is to know if the person being analyzed has chances of marital success in the first place. So, we begin seeing the condition of the planet Venus (the spouse significator for males) in the chart of a man, or the planet Jupiter (the spouse significator for females) in the chart of a woman.
