12th House Synastry: Destiny or Delusion?

Ah, the 12th house.

So notoriously tricky to define. Mysterious and magical, eternal bliss is here- but also realms of imprisonment, addiction, great humiliation. 12th house synastry is no exception; this awakens us to the themes of this house and teaches us to navigate the great wheel of the zodiac, all of the many worlds. Yet tread here with caution! Not with fear, but with caution. Let me explain why.

When I was entering a phase of my spiritual journey I saw the twelfth house shown to me as a vast universe while every other piece of the zodiac was pretty much a grain of sand. There we’ve got countless other dimensions, and nothing operates by familiar earth-bound rules.

Astrologers often talk about dreams and visions when it comes to the twelfth, but that is only scratching the surface. It is in fact a gateway to things that are beyond dreams, beyond any form of human explanation or understanding. If the rest of the houses were primarily defined by Malkuth and the tangible and personal, the twelfth would be Yesod (broadly speaking) and the gateway to what is beyond Yesod even. Your danger here is if you keep concentrating on human rules and egoic expectations, 3D realities.

You will be in trouble if you refuse to go further than a dream, if you have no true spirituality and no desire for God consciousness. If you hold onto these earthly things and all your personal goals and expectations while subsumed in a 12th house experience, you can encounter a lot of unnecessary stresses and hurdles. God looks at you through the things you find in the 12th, but God is behind the material illusion. Keep journeying on!

12th House Synastry: Some details.

But let’s talk about the 12th house synastry in more detail. In this sense, we are obviously talking about overlays. When it comes to overlays, please concentrate more on personal planets- Sun, Moon, Mercury, Venus, Mars. Jupiter and Saturn, also the Nodes and other hypothetical points are of far less importance. Why? Because they move much more slowly. You will share those overlays with pretty much anyone that same age. Also they operate on less of a personal level.

How those factors affect the overlays is going to relate more to how these individuals operate in terms of their social and collective conditioning. It is like… how people your older brother’s age may tend to treat you the same way, because they are Gen X and you are a Millenial.

I won’t give you a blow-by-blow planet-by-planet breakdown because it doesn’t sit right with me. I want you to know the nature of this house and how the overlays operate. Then you can apply that in a general sense to your individual situation. That being said: the overlays.

General rule is- if your planet falls in someone’s house, you have an insight into what’s happening for them in that side of their life. Therefore, if you have a planet in someone’s 12th- you will have some insight into what is hidden, arcane, mysterious- perhaps suppressed within them. This gives you an advantage in a sense as you will be able to delineate any weak spots. But you also may keep that part of yourself in reserve. The person who is the 12th house may be confused, seeking you out- but unable to draw any kind of clarity when they take an overly rational approach. It never does any good to ask “why” when you come here. It is a good question, but rarely draws any answers. Also, if your planets fall in someone else’s 12th, you may lack personal boundaries with them. It may feel “easier” to simply let them have their way. However, it is spiritually harmful to refrain from speaking honestly (and kindly).


If your partner’s planets fall in your 12th be wary of deception. Of course, that can potentially stir all kinds of fears in my readers. This is why I say if you want clarity, don’t go pushing the matter. If you feel that something is not quite all as it seems when there are 12th house overlays in your synastry, you will not draw any clarity by running around in your head trying to sort it out intellectually.

12th House Synastry: An overview.

12th house synastry calls for a spiritual awakening, which calls for self-discipline and self-renewal! Clear your body, mind and spirit of unhelpful habits and go and be of service to someone. Don’t be afraid to share the love, don’t be afraid to share the vibes. However, do not attach to specifics around outcome. You cannot control what specifics might be in your destiny or in your future favour, but you can at least awaken to higher realities and a spiritual path. Any pain that comes from this deception lasts as long as it needs to. This all before it becomes clear that behind the masks of the individual reality, we are all transcendant spiritual beings living in oneness, bliss, harmony. However that awareness cannot be forced, it requires adherence to high principles and the loss of many material illusions.


Remember that the 12th and the 6th are counterparts. The dark side of one and the other are delusion and doubt, the light side of one and the other are faith and acceptance- of life on life’s terms. This is how the 12th can be the absolute liberator or the utter prison house both. You can be fortunate or unfortunate enough to meet them in a relationship. It really is up to you!
