Karmic astrology: south node connections
The most emotionally powerful claim in relationship astrology, and the one to handle with the most care.

First, the answer
In modern Western astrology the south lunar node is read as inherited or past patterns and the north node as growth direction. A contact between one person's planets and the other's south node is interpreted as a past-life connection, often described as instantly familiar. The karmic reading of the nodes is a twentieth-century addition to Western astrology and has no evidential basis.
What the nodes are
Real astronomical points, where the Moon's orbit crosses the ecliptic, and where eclipses happen. Vedic astrology treats them as full planets, Rahu and Ketu. The karmic reading entered Western practice in the twentieth century under theosophical and Eastern influence, and it is routinely presented as ancient.
What south node synastry claims
A contact from one person's Sun, Moon or Venus to the other's south node is read as a relationship carried over from a previous life: immediate familiarity, comfort that arrives too fast, a fated feeling. The attached warning is that such relationships can be regressive, comfortable because they repeat an old pattern.
Past-life connections are where I get off the bus. The nodes are real; the lifetimes are not in evidence.
Why it feels convincing
Instant familiarity is a real experience, and the technique explains it. Node contacts between any two charts are common, so finding one is nearly guaranteed. It's unfalsifiable: a good outcome confirms the bond, a bad one confirms the lesson. And it flatters: a connection across lifetimes beats compatible temperaments.
Why to be careful with it
This is the relationship technique with the most potential to harm. 'Unfinished business from a past life' is an argument for enduring something difficult, and one that can't be examined because the evidence is unavailable in principle. A strong sense of familiarity is information about you, not about a previous life, and not a reason to override what the relationship is like now.
