The planetary nodes
the Sun does not have nodes as it never crosses the ecliptic, and neither does the Earth as it is what makes the ecliptic by its path, but every other planet in the solar system has a south and a north node.
If we apply the same principles to the planetary nodes as we know from the lunar nodes, that the south node represents the origin of the current archetype, and the north node represents the new influences for the archetype to evolve through, it adds a 3 dimensional perspective to each planetary archetype in the chart. Think of it as if you take a picture of a ball in the air, it is equivalent to the picture of a planet in the chart, but if within your picture of the ball also have the picture included of where the ball was kicked off (south node) and where it travels towards (north node), then you will have a better understanding of that ball in the air moment.
Not many astrologers have pondered the meaning of the nodes in depth. Perhaps partly because planetary nodes move so slowly that everyone share their position, they have not been thought important for the individual...Well hold on a minute; everyone shares them so they are not important for the individual, or everyone shares them so they are so important that they are important for everyone?
Having researched the nodes since 2018, I must conclude that without doubt, the answer is yes to the latter. The evidence of the correlation between activity to the collective planetary nodes from the slower moving planets and events that impact everyone, as well as people who influence the collective having planets and points on collective planetary nodes in their birth charts is absolutely overwhelming.
