Ketu — The South Node
Ketu is Rahu's other half — the second of the two lunar nodes, and its exact opposite in every sense. If Rahu is the hungry head chasing the future, Ketu is the body left behind: the south node, the place of what you've already been, already mastered, already outgrown. It's not a planet either — just the second point where the Moon's path crosses the Sun's — but Vedic astrology reads it as one of the most spiritually potent points in the chart.
The Other End of the Axis
The two nodes are a single axis: Ketu always sits exactly opposite Rahu, six signs away. Where Rahu points to what you crave and lack, Ketu points to what you already carry so deeply you barely notice it. In the myth of the severed demon, Ketu is the tail — the body without the head, which is why its nature is instinctive, detached, and turned away from the world. It has already tasted everything Rahu is still chasing, and found it isn't enough. That's the seed of Ketu's spiritual pull: the letting go that comes after the having.
What It Governs
Detachment, mastery, and release. Ketu is the arena of life where you're unusually skilled without trying — talents so ingrained they feel like something carried in from before. Because that mastery is already complete, Ketu also brings a strange dissatisfaction there: you're done with it, even if you can't say why. So it governs renunciation, spirituality, and moksha — liberation, the soul's release from the wheel of wanting. Its shadow is disconnection, avoidance, and the tendency to dismiss or neglect whatever it touches. Its gift is freedom: the peace of no longer needing what you've already outgrown.
Why It's Always Retrograde
Like Rahu, Ketu is a node, not a body, and it moves by the slow backward wobble of the Moon's orbital plane rather than by an orbit of its own. That plane drifts in reverse through the zodiac, so both nodes are permanently retrograde — genuinely moving backward, not just appearing to. It's a fitting motion for the south node: Ketu's whole nature faces backward, toward the mastery and the past you're here to release rather than chase.
In the Chart
Ketu's sign and house show where you're already an old hand — gifted, instinctive, and quietly ready to let go. It's where you may under-invest, precisely because it comes so easily, and where the deepest spiritual growth is available if you stop clinging. Read Rahu and Ketu together: one shows what to reach for, the other what to release. The path of a life runs along that axis.
Ketu is the mastery you brought with you and the attachment you're here to lay down. It asks the quietest question in the chart: what are you finally ready to stop needing?
