North Node & South Node
The two points where the Moon's path crosses the Sun's — the axis of what you're leaving behind and what you're reaching for.
Most of a chart is planets — bodies you could point to in the sky. The Nodes are not that. They are two calculated points, and they carry more weight in a reading than their quietness suggests. Where the Sun says who you are and the Moon says how you feel, the Nodes describe a direction of travel: the thing you arrived already knowing, and the thing this life keeps asking you to learn.
What the Nodes are
The Moon travels its own path around the sky, tilted a few degrees against the Sun's. Two paths that cross must cross in two places, and those two crossing points are the lunar Nodes — the North Node where the Moon climbs above the Sun's path, the South Node where it drops below. They are always exactly opposite each other, a single axis drawn straight through the wheel. Move one and the other moves with it.
Because they are geometry rather than rock, they are computed, not observed. You will also meet two versions: the mean Node, which glides smoothly, and the true Node, which wavers as the real crossing point shifts. They sit close, and a reading will name which it uses.
The South Node — what you came in with
The South Node is the familiar end of the axis. It reads as inheritance: the aptitude that came easily, the role you slip into without thinking, the comfort you reach for when a situation asks for something harder. There is nothing wrong with it — it is genuine skill, well practised. The catch is that it is practised to the point of default. Leaned on too heavily, the South Node becomes the groove you keep sliding back into, the safe move that quietly keeps a life the same size.
The North Node — where you're growing
Directly opposite sits the North Node, and it feels like the opposite: unfamiliar, a little uncomfortable, not yet fluent. This is the growth edge — the direction the chart seems built to reach toward, the qualities you were not handed and have to develop on purpose. It rarely comes naturally, which is exactly the point. Progress along the North Node tends to feel like effort first and, later, like the thing you are most glad you did. The two Nodes read as one sentence: where you have been, and where you are being drawn.
The axis by sign and house
Like everything in a chart, the Nodes take their meaning from where they fall. The sign describes the quality of the pull — a North Node in a fire sign asks for a different kind of courage than one in water. The house names which room of your life the growth is asked in: partnership, work, home, the private inner ground. And because a house depends on your Rising, and the Rising on your exact birth time, the Nodes are only placed accurately when the hour is known. Guess the time and the whole axis can swing into the wrong pair of rooms.
Why they anchor the Soul Contract reading
This is why the Nodes sit at the heart of the Soul Contract reading. That reading stays with the fixed chart rather than the passing season, and the nodal axis is its spine — the through-line the deeper points are read against. Alongside Chiron, Saturn, and Pluto, the Nodes describe not your year but your shape: what you carry, and what you are here to grow into.
If you would like to see where your own axis falls — which sign the South Node holds and which direction the North Node is drawing you toward — start with your birth chart. And if you are still getting your bearings on how any of this is read, what astrology is is a calm place to begin.
