Rahu is the Moon's north node, a shadow planet that stands for craving, novelty, the foreign and the drive to have more. It moves backward through the zodiac with Ketu opposite. In Libra, a cardinal air sign ruled by Venus, Rahu's friend, the craving is for partnership, foreign alliance and a fairness that is new rather than inherited.
With Ketu in Aries, the lone warrior and the impulse to go first are what the world is releasing. The theme is relationship redefined. Alliances form across old lines. Justice is argued in new terms. The lesson is that wanting a partner is not the same as being one.
