The composite Sun in the third house puts the relationship's energy into talking. Robert Hand reads it as favouring connections where communication and the exchange of ideas and opinions matter most. In business it points toward commerce and the communications field.
For a personal relationship he says the position has great strengths and great weaknesses, and he lays out both without softening either.
What This Placement Describes
The third house is the house of the everyday mind: communication, the routine daily environment, and relatives. Hand treats communication as the part that matters most in a composite. If two people cannot communicate, they are in real trouble, and the third house is where that shows.
He also describes the third as the house of the lower mind, meaning the mind in its habitual operation. Habitual thought patterns, unquestioned opinions, unexamined notions. The composite third house says a great deal about how those patterns will run inside the relationship, and whether they will bind the two together or grind against each other. He notes that people are frequently not aware of their own habitual attitudes at all, which is why a neutral third party is often what it takes to bring them into the light.
A relationship with a strong third house typically comes about through mental affinity. The two enjoy talking with each other and trading ideas, and that enjoyment is the substance of the bond rather than an accessory to it.
How It Tends To Play Out
The strengths, in Hand's account, are considerable. The pair can communicate well, share many of the same ideas and opinions, and speak openly with each other. There are few barriers to mutual understanding, with the possible exception of the emotional level. Conversation between them is a genuine pleasure rather than a chore.
That capacity carries over into trouble. Hand notes that a strong commitment to communication helps this pair approach whatever problems they have to face together, which is not a small advantage. He rates the mental rapport as unusually good, better than many couples manage.
He also says plainly that the third house is a better position for friendship than for a love affair, because relating happens by talking rather than by feeling.
The Opposite House
The farther midpoint retains some influence, increasing as the two natal Suns approach opposition, so a third-house Sun asks to be read through the ninth as well. Near opposition, Hand treats this as essential rather than a refinement.
The ninth house is the overall view of the world the two people take together. It broadens them, exposes them to new ideas, and pushes them to think across a wider spectrum than before. Where the third is the daily mind and the shared assumption, the ninth is the mind reaching for meaning. Reading the pair together turns the same solar emphasis into a question: is the constant exchange circling the same familiar ground, or is it taking the relationship somewhere.
Hand gives no threshold for when to switch weight from one house to the other, and no method for blending them. Both readings stand.
Where It Gets Difficult
The great weakness Hand identifies is that even a personal relationship here will run mainly on the intellectual level, and it is not likely to be a profound emotional tie.
The mechanism is specific. When an emotional situation arises, the pair is inclined to intellectualise it, to try to figure it out rather than live through it and learn from the experience. Hand insists that the knowledge gained by living through something cannot be replaced by logical analysis. It is exactly the lesson a third-house Sun makes hard to learn, because the placement inclines the relationship toward analysis in the first place.
He is careful not to condemn an intellectual relationship as such. There is nothing wrong with one. There are simply times when it is the wrong instrument, and the discipline this placement asks for is to notice those times and not stop at the mental level.
House position sets the issue. The manner in which the two handle it is described by the aspects to the Sun, which is a separate question from the house.
