Some things in life are universal; a desire for love and the search for a soulmate is a common human experience. Soulmate means different things to different people. However, various determinators in astrological synastry play a role in the soulmate phenomenon.

The Role of Synastry

Astrological synastry is the art of comparing natal charts to find strengths and weaknesses in the area of compatibility. There are key soulmate aspects in synastry that can denote possible astrological soulmates. The more harmonious connections (conjunctions, trines, and sextiles) between birth charts, the greater the possibility of a blissful soul mate relationship.

The Sun to Sun Aspects

In astrology, the sun represents the core of your personality, who you really are. Harmonious aspects between the suns in two birth charts are an indicator of compatibility. You get along well and have similar traits. The problem with using the sun-to-sun aspects in soulmate synastry is that many people are born on the same day. You have to look deeper than the sun sign to find potential soulmate connections between two horoscopes. Within the context of soulmates, compatibly between two sun signs is "almost" irrelevant. It's also important to note that if two individuals were born during the same year and on the same date, they will have many connections in their synastry. Only their moons and rising signs are likely to be different.

The Sun and Personal Planets

However, suppose someone has a personal planet conjunct your sun in synastry (and vice versa). In that case, there is often a strong attraction that pulls you together. The sun conjunct the moon or Venus in another person's horoscope is a possible indicator of a soulmate connection.

Sun and Moon Aspects

Some would say that harmonious sun and moon aspects are the Holy Grail for zodiac soulmates. The sun and moon naturally complement one another; they are meant to be together. With this connection, an immediate attraction is felt. As the relationship evolves and deepens, the "moon" person usually evolves into a supporting role to the "sun" person who tends to give light to the "moon" person's life.

Moon to Moon Aspects

The moon is associated with emotions, instincts, deep needs, and nurturing. It's one of the most essential features of the natal chart. Moon conjunct, trine, or sextile moon can be an indicator of soulmates in astrology. Moon compatibility supports emotional understanding and caring in the relationship.

Venus and Mars Aspects

Venus (love) and Mars (sex) are the planets that draw you into intimate relationships. When your Venus is conjunct, trine, or sextile your lover's Mars or the other way around, it's a potent aphrodisiac that can spark almost instant soulmate attraction. This connection is the very best signature of a soulmate relationship that's loving and sexually fulfilling.

Personal Planets Conjunct the Ascendant

If a person has a planet conjunct your rising sign, there is a strong attraction between you. The "planet" person is attracted to the "ascendant" person's outer persona and physical appearance. The "ascendant" person perceives the "planet" person as relevant to the nature of the planet. For example, synastry that involves Venus conjunct rising sign is one of the strongest indicators of mutual attraction.

Planets Aspecting an Angle

The angles are a crucial part of the natal chart. There are four angles in astrology: the ascendant, the descendant, the IC, and the Midheaven. If someone has a planet conjunct one of your angles, you definitely feel it. These are common synastry aspects for soulmates in astrology.

Planets in the Seventh House

The seventh house is the most essential house when it comes to committed partnerships and one-on-one relationships. Planets in your partner's seventh house can indicate a strong bond. You see this person as your ideal partner. This is especially true for the sun, moon, or Venus.

The Role of Saturn

Saturn aspects, as they pertain to astrological soulmates, are considered "the tie that binds." It's always nice to see some positive Saturn aspects in a marriage chart, since this bodes well for a long-term commitment. The only pitfall here is that it can sometimes turn into a heavy responsibility or a burden. To clarify, even if the two of you break up in the future, there may still be a connection there or feelings of responsibility that both may still have to contend with.

Spiritual Soulmates

Most individuals believe that soulmate love is a blissful and perfect love that lasts a lifetime. But in a metaphysical sense, a soulmate relationship has little to do with ideal love or bliss. Growth is the key focus of these spiritual soulmate relationships. These relationships may be blissful, but they are also challenging, addictive, intense, passionate, and life-changing. Essentially, some spiritual soulmates come into your life to help you grow in love and wisdom, while others are there to aid you in learning difficult life lessons.

When Spiritual Soulmates Meet

There's intense and potent magic at work in a spiritual soulmate relationship. Regardless of the other connections in their birth charts, spiritual soulmates have a timeless bond. Even if they've been apart for years or several lifetimes, they're irresistibly drawn to each other when they meet again. Each feels excitement and anticipation and senses that they've known the other forever. These soulmate relationships can be blissful in the beginning, but it won't take long before the drama sets in.

The Lunar Nodes and Spiritual Soulmates

Evolutionary astrologers believe that the moon's Nodes are the single most powerful indicator of a spiritual soulmate connection. A connection between planets and the South Node (☋) indicates a past life connection and issues the couples must work out in this lifetime. A connection between planets and the North Node (☊) suggests that the two have a mission to accomplish together in this life. The best spiritual soulmate connection to look for in synastry are planets that are conjunct a node.

One birth chart is complex, and comparing two charts for soulmate synastry is even more complicated. You can calculate a synastry chart bi-wheel free online at Astroseek.
