Zodiac Compatibility

Zodiac signs compatibility

+

Once you get to know your own Sun sign and full chart well, you will probably want to know how your energy relates to the energy of other people in your life. Zodiac compatibility is understood through numerous techniques. The simplest and most straightforward technique compares one Zodiac sign with all the other Zodiac signs to understand and measure compatibility. Keep in mind that every point in the sky is in a particular sign at the time of birth. While your Sun may be in Aries, your Moon might be in Capricorn. As you delve deeper into the compatibility question, you will want to compare full charts, not just Sun signs.

Zodiac Sign Compatibility

Let us start with just the signs and how they interact based on their qualities. Every sign has an element and a modality. Aries is a fire sign; and its “mode” is cardinal, which initiates. Taurus, the next sign, is ruled by the element of earth; and its “mode” is fixed, which establishes. Certain elements and modes work well and easily together, while others struggle and challenge one another. Below is an excellent image that maps out compatibility among the signs.

Aries Compatibility

Aries is a fire sign. Aries is the sign for new beginnings, independence, maverick action, and pioneering. Often known as “the warrior” or “the risk-taker”, Aries connects to the world through its boundless energy to explore, play, compete, and initiate. This sign rules survival, the ego, and the self.

Someone with an Aries Sun, Moon, or Ascendant (but especially the Sun) will seek to chart their own path as a role model for the world, humankind, and all of life; by being who they need to be, they encourage others to be themselves, authentically.

Aries is most compatible with the other fire signs: Leo and Sagittarius; and is one of the few signs that matches well itself.

Taurus Compatibility

Taurus is most compatible with the other earth signs: Virgo and Capricorn; and it matches well with Libra because Venus rules Taurus and Libra.

Combining Charts

Moving beyond the basics of matching Sun signs, there are three methods to compare and combine charts.

Synastry

Synastry is the word used to describe comparing two charts. It is probably easier to show it visually rather than write a lengthy explanation. Below you will see a single image of two charts, one on the inside and another going around the outside. There are two images to show what the relationship looks like when person A is on the inside and person B is on the outside, then the reverse.

Relationship A to B
Relationship B to A

These were randomly generated charts. As you can see, all the same points appear in different signs throughout the two charts. When we look at them together, we have the chance to see the kinds of energy dynamics that will take effect when they form a connection, whether as lovers, friends, or family members.

The Composite Chart

There are two main ways to combine astrology charts: the midpoint method, known as the Composite chart, and the geographic method, known as the Davison chart. Below is an example of the Composite chart for Person A and Person B. This chart reflects the energetic entity the two people become when they are together. The Composite chart exists for any connection between two people, so there can be a Composite chart for parents and children, co-workers, and friendships.

Relationship Composite A and B

The Davison Chart

The Davison chart is the second method for combining two charts into one. Below you will be able to see the Davison chart for Person’s A and B and the Location Map of their Midpoint in Space.

When you combine the charts, the couple ends up with the Sun Leo at 14 degrees and 08 minutes in the 3rd House of Communication. The combined Moon is 11d50m of Capricorn and the Ascendant is 21d00m of Gemini. The Primary Triad for this couple could be stated as, “Their Life Path needs to be adventurous and filled with dynamic interactions with the people around them, as social leaders. At the heart (Moon) of the relationship is the soul urge to succeed together as a couple. People will perceive them together as open-minded and curious, the type of couple everyone likes to communicate with.”

Compatibility and the Elements

All signs can relate to one another successfully, but some have more flow with each other while others relate by struggling with one another, which encourages growth. The flow or struggle is largely determined by the dynamic between the elements. All signs flow with their own element. A fire sign like Aries relates easily to Leo, another fire sign. Scorpio relates easily to Pisces, and so on.

Certain elements complement one another, which is the case with fire and air signs, and earth and water signs. Struggle, or “work to be done”, happens when fire meets water and earth, air meets water and earth, water meets fire and air, and earth meets fire and air.
