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 Taurus, a fixed earth sign ruled by Venus, the tradition calls Rahu exalted: appetite in the sign of wealth, land, food and pleasure, where wanting more is the nature of the sign.
With Ketu in Scorpio, secrets, debts and shared power are what the world is releasing. The theme is material hunger that gets what it wants. Markets and tastes swing wide. The lesson is that plenty can be a kind of fever, and that value is what remains when the fever breaks.
