The fourth house is in some ways the most natural position for the composite Moon, because of the strong analogy between this house and Cancer, the Moon's own sign. Robert Hand says as much before he says anything else about it.
What follows from that is a relationship organised around shared background, shared feeling and, very often, a shared roof.
What This Placement Describes
Hand's general treatment of the composite fourth house widens it well past housing. It shows the roots of a relationship both literally, in geographic terms, and figuratively, in terms of mental and emotional background. It signifies the innermost depths of a connection, which may lie so far inside as to be invisible at the surface. It is the house to check for underlying compatibility: whether two backgrounds fit, and whether two sets of basic emotional and psychological characteristics fit.
With the Moon there, sharing a common background or experience becomes extremely important, because it is likely to be a strong force binding the two together. Hand describes the feeling this produces with unusual vividness. The two may feel that they are alone together in a crazy world, protected only by their shared attitudes and origins.
He then makes a qualification that matters in practice. It is not so important that the two backgrounds be genuinely similar as that they have produced similar basic attitudes to the world. Two people from very different starting points can meet here perfectly well.
How It Tends To Play Out
Even more than with a second-house Moon, the two are together to give each other emotional security. Hand says that security is very likely to take the form of shared real estate or a shared house, and he rates the placement as an excellent position for marriage partners or roommates because of the strong sense of sharing it induces.
The formulation he settles on is that a fourth-house Moon is most favourable in a relationship where two people set up housekeeping together, which is why he calls it a good position in the chart of a marriage.
The daily texture of it is domestic in the broad sense. The relationship builds an inside, a place with its own habits and its own atmosphere, and both people draw on that.
The Opposite House
Because the farther midpoint keeps some effect, and that effect grows as the two natal Moons approach opposition, a fourth-house Moon should also be read through the tenth. Where the natal positions are near opposition, Hand treats reading both as essential.
The tenth house is the outward reality of a relationship: its direction, its purpose, its standing in the world. Hand's own note on the tenth-house Moon is the useful contrast. There the danger is seeing everything in terms of externals, when feeling should be an internal concern between two people rather than something outside them. The fourth-house Moon has the opposite gravity. Reading the axis whole asks whether a relationship this rooted has any direction, and whether the two ever look up from the life they have built to ask what it is for.
He gives no threshold for when the tenth reading takes over and no method for blending the two. Both are read.
Where It Gets Difficult
Hand issues two warnings and calls the first one necessary.
The desire for emotional security, and the material security that tends to follow it, should not become the only thing holding the two together. Security is a real good here and it is also the placement's most available substitute for everything else.
The second is more specific and more useful. The need for a secure relationship must not lead to repressing the legitimate complaints the two have with each other. His instruction is to let your partner know how you feel, on the grounds that the relationship is probably strong enough to stand the strain. That last clause is the point. A fourth-house Moon builds a bond that can carry honest friction, and the temptation is to protect the calm instead of using the strength.
A third pressure sits in the house rather than in Hand's warnings. This is a subjective position, and a relationship that spends most of its life indoors with itself can lose track of how it looks from anywhere else.
The house sets the issue. Whether the shared inner life is warm or stifling is described by the aspects to the Moon, which is a separate question.
