Nodes describe your whole incarnation. I mean that the South Node of your past describes a great deal of what qualities and events you’ve brought to this lifetime, and the North Node tells what you’re likely to do with them, to put it simply.
The Moon’s Nodes constitute a mini-chart and offer Solutions and descriptions of what you came to this life equipped with, along with your goals and intentions.
Growth comes from utilizing the best of the South Node to augment and develop the skills of the North Node. It’s a balance. Too much of the South Node or knee-jerk use of it is a rut—the same trapping patterns from the past.
What’s interesting and mystifying is that the Nodes are not bodies like a planet, asteroid, or Star. They’re intersecting points of two Great Circles: The Ecliptic (the path of the Sun and planets) and the Prime Meridian (the Great Plane that is implied by the perpendicular circle to the Equator.
In other words, a Node is a “crossroad.”—an intersection like where two ships seem to have crossed the same point. The point has NO substance, but the impact in our lives does, a great mystery.
I recommend two magnificent books on the Nodes:
1. Jan Spiller’s Astrology for the Soul
2. Martin Schulman’s Karmic Astrology: The Moon’s Nodes and Reincarnation
Spiller is a How-to for your life. Schulman takes you into your messy depths so that you can come out a Saint.
