Ketu is the Moon's south node, a shadow planet with no body of its own. It stands for letting go, the past, sudden endings and the turn inward. It moves backward through the zodiac, and Rahu always sits in the opposite sign, reaching for what Ketu releases. Pisces is a dual water sign ruled by Jupiter, a friend to Ketu, so the planet is at ease here: the sign of faith, dreams, the sea and the end of a cycle. Both lean toward the inner world.
With Rahu in Virgo, method, health and the technical fix are what the world is reaching for. On the Ketu side, illusions lose their hold. Some escapes close down, and some spiritual paths deepen. The lesson is that letting go is a skill, and that this sign teaches it more gently than most.
