Rahu is the Moon's north node, a shadow planet that stands for craving, novelty and the drive to have more. It moves backward through the zodiac with Ketu opposite. In Cancer, a cardinal water sign ruled by the Moon, the craving is for home, belonging and emotional safety. The Moon and Rahu are not friends in the tradition, so the longing is restless and hard to satisfy.
With Ketu in Capricorn, structure, hierarchy and the authority of the state are what the world is releasing. The theme is emotional politics: homelands, migration and the question of who belongs. The lesson is that a craving for safety can make people cruel, and that home is built as much as found.
