Please explain the meaning of the different aspects: opposition, square, trine and sextile.
At the most basic level, aspects simply describe the angle between two celestial bodies. Their astrological interpretation developed later, from the observation that certain angles repeatedly display similar dynamics.
It is useful not to regard aspects as “good” or “bad.” They describe different ways in which two psychological forces relate to one another.
Opposition (180°)
The opposition is the aspect of polarity.
Two principles face each other like two people sitting on opposite sides of a table.
They see one another. They influence one another. But they often want different things.
The feeling is:
> “I somehow have to bring both together.”
Sun opposite Saturn:
Vitality ↔ responsibility
Self-expression ↔ self-control
Moon opposite Uranus:
Security ↔ freedom
The opposition creates awareness.
One often first recognises something in the outside world.
One encounters people who embody one pole while living out the other oneself.
The developmental task is:
> Do not choose between them; connect them.
---
Square (90°)
The square is the aspect of friction.
Two forces want to act at the same time, but in different directions.
The feeling is:
> “The way things are, this does not work.”
This creates tension.
But it also creates movement.
People with many squares often develop tremendous abilities because they are constantly compelled to find solutions.
Mars square Pluto:
Will meets power
Assertiveness meets issues of control
Jupiter square Neptune:
The search for meaning meets illusion
Hope meets reality
The square asks:
> What do you need to learn so that these forces can work together constructively?
---
Trine (120°)
The trine is the aspect of flow.
Two principles understand each other intuitively.
They speak the same language.
The feeling is:
> “I can simply do this.”
Moon trine Lilith:
Feelings and instincts support each other.
Mars trine Saturn:
Drive and discipline work together.
The strength of the trine is ease.
The danger of the trine is complacency.
Because we often develop what comes easily to us less consciously.
The trine asks:
> Are you making use of your talent at all?
---
Sextile (60°)
The sextile is often an underestimated aspect.
It connects two forces that could work well together but do not do so automatically.
The feeling is:
> “There is an opportunity here.”
Mercury sextile Moon:
Thinking and feeling can work together.
Venus sextile Mars:
Attraction and action complement each other.
The sextile is like a door.
It stands open.
But you have to walk through it yourself.
That is why sextiles often become active only when a person consciously makes something of them.

An image
Imagine four people building a house together.
Trine
They understand each other immediately.
No one needs to explain much.
The work flows.
Sextile
They understand each other in principle.
But someone has to initiate the project.
Square
They constantly clash.
Yet precisely because of this, new ideas and solutions emerge.
Opposition
They sit at opposite ends of the table and represent opposing positions.
If they listen to each other, a more complete picture emerges.
If they do not, conflict ensues.
---
In your language:
The trine loves trust.
The sextile loves possibilities.
The square loves development.
The opposition loves awareness.
Or, more briefly:
The trine says: “I have this.”
The sextile says: “I could do this.”
The square says: “I have to learn this.”
The opposition says: “I have to understand this.”
That is why oppositions and squares are often the aspects one remembers throughout one’s life, while trines and sextiles are frequently the forces that make it possible to meet those challenges in the first place.
My choice of words for the opposition would be: I have to become aware that someone is sitting on the other side of the table. I should not forget them.
So the work is becoming aware.
For the square: I have to keep working so that both function together. So the work is the work itself.
Yes, that is a very apt distinction.
Many astrological descriptions lump oppositions and squares together because both create tension. But the tension feels entirely different.
Opposition: the work is becoming aware
In an opposition, two figures really are sitting at a table.
The initial problem is not that they are fighting each other.
The problem is that one often identifies with one side and overlooks the other.
The task is:
> “Someone else is sitting there too.”
When the other side remains unconscious, it frequently appears in other people.
For example, one then experiences:
freedom in one’s partner (Uranus)
strictness in one’s boss (Saturn)
emotionality in one’s friends (Moon)
The opposition asks:
> Can you acknowledge that this too belongs to you?
That is why I like your wording:
> The work is bringing it into awareness.
The first step is not resolving the conflict, but perceiving the second voice.
---
Square: the work is the work
Here the figures are not sitting at a table.
They are more like people pulling the levers of the same machine.
And when one moves something, the other jams.
The problem is not a lack of awareness.
One usually feels both sides very clearly.
The problem is:
> How do I make this work in practice?
That is why people with strong squares often feel:
> “Why do I have to keep working on this issue?”
Because the square has no final solution.
It demands continual adjustment.
I therefore like your wording very much:
> The work is the work itself.
---
Or, more succinctly:
Opposition:
> “Oh, you are still here too.”
Square:
> “Damn, we have to work together again.”
---
If I take your own chart as an example:
Sun opposite Saturn
Here I would indeed say that the decisive step, again and again, is to perceive Saturn at all, rather than seeing only the Sun, or vice versa.
The actual development is:
> “The critic is part of me.”
“The vital one is part of me too.”
Pluto square Mars
That feels entirely different.
Usually it is clear from the outset that both are present.
The will (Mars) and the themes of power and control (Pluto) can be felt.
The question is not:
> “Does Pluto even exist?”
but:
> “How do I deal with it today?”
That is the work of squares.
One might even express it poetically:
Oppositions want to be seen.
Squares want to be worked on.
Trines want to be used.
Sextiles want to be seized.
These are four very different kinds of “work.” And your distinction between bringing something into awareness and doing the actual work captures the essence of opposition and square very precisely.
The conjunction is still missing from the list of aspects I consider important. Please expand the discussion accordingly.
That is indeed an important addition. In some respects, the conjunction is even the most fundamental aspect, because here no relationship between two separate forces arises at all — they begin in the same place.
I would therefore describe it differently from the other aspects.
The conjunction
In a conjunction, there is initially no dialogue at all.
The two planets do not speak to each other.
They speak with one voice.
That is why it is often difficult to distinguish between them in the first place.
A person with Sun conjunct Mercury frequently does not experience:
> “Now I am thinking.”
and then:
> “Now I am being myself.”
Instead:
> “To me, these are the same thing.”
Only with growing awareness can the two functions be differentiated somewhat.
---
The task of the conjunction
While the opposition calls for awareness of the other pole, one could say of the conjunction:
> The task is differentiation.
First one has to learn:
> “This is Venus.”
> “This is Jupiter.”
Even though both appear as a single force.
---
Your conjunctions
Your own chart illustrates beautifully what this means.
Moon – Venus – Jupiter
You have often described these three planets together.
Perhaps because they do not feel like three different forces to you at all.
Feeling (Moon), love (Venus) and meaning (Jupiter) form almost a single movement.
When you speak of beauty, feeling almost always resonates within it.
When you speak of insight, enthusiasm almost always resonates within it.
When you speak of love, meaning almost always resonates within it.
That would be typical of a close conjunction.
---
Saturn and Mars
By contrast, you have always described Mars and Saturn as two different actors.
That fits remarkably well.
They are in a trine.
Two individuals remain, and they work exceptionally well together.
You once said, in essence:
> Mars acts.
> Saturn makes something lasting out of it.
That is almost the language of a trine.
---
A new image
Perhaps all the aspects could be described as different kinds of conversation:
Conjunction
> We speak at the same time.
It is hard to hear who said what.
Trine
> We understand each other without many words.
Sextile
> We could do something together.
Square
> We are constantly arguing.
Opposition
> We sit opposite each other and first have to acknowledge that the other person exists.
---
A small addition to your way of thinking
I notice that you increasingly understand aspects as processes.
Not:
> “A trine means talent.”
but:
> “A trine is a particular way in which two principles relate to one another.”
I consider that a fruitful approach.
Perhaps it could be extended further:
Conjunction: identity — we experience ourselves as one.
Trine: trust — we work together effortlessly.
Sextile: invitation — we can work together if someone takes the first step.
Square: development — we have to keep reorganising how we work together.
Opposition: awareness — we first have to recognise that both of us belong.
What I particularly like about this is that every aspect describes its own form of relationship. It is no longer about “good” or “bad” aspects, but about different relationship dynamics between the archetypal forces in the chart. That also fits your way of understanding a horoscope less as a collection of separate symbols and more as a network of principles communicating with one another.
