Hi, Joayn,

I had a section on Chiron in Synastry in my Chiron book, so allow me to copy and paste it here:

"SYNASTRY
When I first began to compare charts, looking for aspects from one person’s Chiron to the chart of the other individual, I expected to find this only occasionally. I also expected that, when I did find it, the relationship would have something extreme or unique about it---something to set it far apart from other relationships. Well research has proven me very wrong on the first count---and almost as far off on the second.

I have been amazed at how common Chiron aspects appear in Synastry. In fact it seems to appear more often than not. I have a theory about why but will go into that later.

As for the nature of such [Chiron-marked] relationships---they usually seem to have no initial differences from other relationships, at least superficially. However, when you look deeper you begin to see that there is a difference, and the difference is in how open the people are to each other. Let us look at a few different aspects in order to make this clearer.

CONJUNCTION
If you have your natal Chiron in conjunction to a planet in another’s chart, there is automatically some type of attraction, usually mutual. And the area of attraction fits the nature of the other planet. The attraction is not of sexual nature, unless the other planet is something like Mars or Venus. Rather, it is the attraction toward someone who seems to be travelling along the same path---a kindred spirit in some fashion. And, [here is a crucial point], what happens next depends a great deal upon the type of relationship, but even more, on the person’s self-image. IF each individual is fairly well-balanced, an excellent relationship can develop here with a feeling of being true equals in whatever area the planet represents. This is truly a good thing in romance, as you can imagine. It can be very positive in teacher/pupil and parent/child relationships because both feel free to learn from the other. BUT, if one of the individuals feels severely lacking in this area, or in need of help, that person turns to the other as a teacher, or guide, and seeks the other’s ‘superior wisdom.’ As you can imagine, this would be of benefit in counseling, or parent/ child---but can be a possible hazard in such relationships as marriage. Given enough time the Chiron aspect tends to equalize differences, and so the two people have a chance to grow eventually to feel equal here. But, until then, it is possible to build up resentment against the very person from whom you are seeking help.

No matter which type of relationship this is, one thing seems especially to be true---the planet that is aspecting Chiron from one chart to the other seems unable to keep up defenses to keep the Chiron person out. It is as if, for the Chiron person, the walls around the other come tumbling down---or at least the Chiron person has little trouble getting inside the walls the other person has built around self. And depending on how thick those wails were initially, and how dependent the person was on the security provided by the walls---such openness can be felt as truly fantastic, or extremely frightening. Especially since the person being aspected by the other’s Chiron cannot develop any other way to erect wails around his/her planet.

SQUARE
Here we have something similar to the conjunction, but with a twist. There seems to be an attraction, yet a repulsion at the same time. This mixed feeling seems to be much stronger in the Chiron person than in the other individual. The Chiron person also seems to have the initial effect of getting past the other’s defenses---but frequently causes resentment in so doing. The person being aspected by another’s Chiron becomes capable of developing new defenses to keep the Chiron person out---but then the Chiron person becomes able to get through these new defenses, as well. Therefore, if the people are insecure, this aspect turns their relationship into a battlefield. Yet even so, both people grow because of it. Positively an awareness dawns about what is going on---and the two develop a relationship with great growth potential. They perceive the process of throwing up new walls as attempts to focus on insecurities. They do not feel threatened by them, but see them as a way of clearing out the rubbish. The result---mutual growth and increasing closeness.

OPPOSITION
Between any two planets, an opposition is an exchange. It can become a war, or a partnership. When Chiron in one person’s chart opposes a planet in the chart of another person, the word ‘exchange’ takes on a very specific meaning: each person tends to take on qualities of the other. For example, let us say that one person’s Chiron opposes the other person’s Mars. The Chiron person will become more aggressive, more active, and tend to be somewhat physically attracted to the other person. The Mars person will become more individual, more of a Maverick, and more willing to open up and try new things. This can be a very positive thing, especially if each needs to grow in the area ruled by the opposing planet. If the Mars person needs to get out of ruts, or the Chiron person needs more self-assertion, the relationship can be really fantastic. However, if a person is afraid of the qualities s/he gets from the other---or is already active enough in those areas, the relationship can become extremely uncomfortable for one or both parties.

OTHER ASPECTS
Trines and sextiles from Chiron in one chart to planets in another chart also denote some of the same attraction, but the intensity is much less than with the hard aspects. There is also somewhat of a lowering of the defenses, but also not to such a drastic extent. These are good aspects to have between charts if there are other positive aspects, but alone they are not dramatically significant. Much more study is needed here.
