The old fashioned/general way to determine if two people were compatible was to just see if the Sun Signs were in elemental harmony. The Sun Sign indicates a person’s personality. The Moon Sign is more imperative, because it determines one’s emotional nature. Venus influences a person’s love nature. Mars is responsible for an individual’s drive and energy. Merury rules the intellect and communication. The Rising Sign governs how a person looks and how the person is seen by others. Hence, to determine compatibility, all the major planets and aspects have to be looked at to see how compatible or incompatible two people are.
The Fire Signs: Aries, Leo, Sagittarius. They are passionate, impulsive, creative, restless, bold, candid, tempermental.
The Air Signs: Gemini, Libra, Aquarius. They are intellectual, creative, comunicative, rational, romantic, futuristic.
The Earth Signs: Taurus, Virgo, Capricorn. They are reliable, practical, sensual, determined, hard working.
The Water Signs: Cancer, Scorpio, Pisces. They are intuitive, psychic, creative, emotional, compassionate, romantic, easily hurt and prone to get violent as a result.
The modalities of the signs, Cadinal, fixed, mutable. The Cardinal Signs likes change, to be in control and start new projects. Aries, Libra, Cancer, Capricorn are in that group.
The Mutable Signs are adaptable, likes variety, are dual sided, multi-tasking. They are Gemini, Sagittarius, Pisces, Virgo.
The Fixed Signs are stubborn, do not like change, hard working, able to finish what they start. They are Scorpio, Taurus, Leo, Aquarius.
Generally, an Aries and a Cancer couple would not have alot in common. They would need one or more major planets in each others sign. For example, if the Aries has Moon in Cancer and Venus in Pisces, that would add some compatible (water) influence which a Cancer needs. Another possibility is if both had their Moons in the same sign or element. Moreover, if the Rising sign of one opposites the others Sun, or both Risings are in elemental harmony. And so on.
If you have a question regarding compatibility, I will be happy to answer. I have some extra time, and I need to practice anyway. I have a Forum in Off Topics here at word Press. Or you can e-mail me at: dcsilverstar1@GMail.com.
