Do You Know, “Females are from Venus and Men from Mars”? And the description finds its root in Astrology.
In Astrology Mars is male and Venus is a female. When these two planets join corporally , then a relationship of man and women starts, and in a chart when they join, facet each other, or Mars overcomes the impact Venus in any degree or manner, in the birth chart or the Navamsha chart, it amounts to higher sexuality in the native.
Now the question, why husbands and wives always have a difference in opinion?
Have you observed that the signs owned by Mars and Venus? These are 7th and also 12th from each other.
Seventh is the appreciative house, but the twelfth house is the natural house of resistance. Mars, therefore, overcomes or dominates Venus and stands on many matters opposed to what Venus signifies. Thus, there is an opposition between the two planets in the above sense.
The disparity between Venus and Mars is obvious as far as the emotional side of the human nature is involved. Venus is emotionally sentient whereas Mars is emotionally excitable. Therefore, Venus procreates emotional impressions but Mars projects passions. Affection and refinement thus fall within the domain of Venus. Mars governs aggressiveness.
