How it works: The lunar nodes are calculated using the mean longitude formula of the Moon's ascending node: Ω = 125.04452 − 1934.136261·T + 0.0020708·T² + T³/450000, where T is centuries since J2000.0. The North Node is where the Moon crosses the ecliptic from south to north (your karmic direction), and the South Node is exactly 180° opposite (past-life comfort zone).
