Rahu is the Moon's north node, a shadow planet that stands for craving, novelty, technology and the drive to have more. It moves backward through the zodiac with Ketu opposite. In Virgo, a mutable earth sign ruled by Mercury, Rahu's friend, the craving turns to detail, health, work and the technical fix for every problem.
With Ketu in Pisces, faith, surrender and the acceptance of what cannot be fixed are what the world is releasing. The theme is anxiety made productive. Health is scrutinised. Work is measured. The lesson is that analysis can become obsession, and that some things are healed rather than solved.
