Ketu

Ketu (ketu) is the south node of the lunar orbit, the shadow graha of detachment and closure — ninth in the count of the navagraha. Ketu has no body; it is the computed point where the paths of the Sun and Moon cross, and so it marks not light but its ebbing — the pull to let go, to finish, to step back. When a day's quality is colored by Ketu, it leans toward sorting through and parting with the old, rather than toward new outward beginnings.

Place in the system

Ketu is one of the nine grahas and, together with Rahu, forms the pair of lunar nodes: the two points where the Moon's orbit crosses the Sun's visible path. The nodes always stand opposite each other, 180° apart, and move backward across the zodiac on average; the true node, which this site calculates, regularly has brief stations and stretches of direct motion, though the net drift over time remains backward. Rahu is the north, ascending node; Ketu the south, descending one. Where Rahu pulls outward and grasps, Ketu draws inward and releases: one axis, two opposite ends.

Ketu does not own a rashi sign of its own — the shadow grahas hold no rulership over signs, and classical Parashara assigns the nodes no sign lordship and no mulatrikona; some later texts do assign the nodes co-rulership of certain signs, but this is not a widely accepted position. By temperament, the classics liken Ketu to Mars: sharp, severing, penetrating. By nature it is counted among the harsh grahas.

Under Vimshottari, Ketu rules three lunar mansions — Ashwini, Magha and Mula — and is given a period of seven years, one of the shortest in the dasha cycle. Schools disagree on where Ketu strengthens and where it weakens: some place its exaltation in Scorpio, others in Sagittarius, and there is no single canon here, since Parashara himself leaves it unspecified for the nodes.

Practical meaning

Ketu is the karaka of detachment, rupture and culmination. It is the graha of what has already been passed through and no longer holds: finished experience, letting go of the excess, stepping aside. Where Rahu shows insatiable hunger and the alluring new, Ketu shows satiety, the point at which a person cools toward old attachments on their own. Ketu's symbol is a banner and a headless body: action without a reasoning "I," movement by instinct rather than calculation.

Ketu is linked to a particular kind of insight — not analytical, but sudden: unexpected realization, a sense for the hidden, an interest in roots and in what lies beneath the visible. From this comes its darker side too: distraction, doubt, a sense of lack and loss even where, outwardly, everything is in place, and sharp breaks and partings. Ketu does not build outward — it clears and unties, and this is where its use lies: having stripped away what has outlived itself down to the root, it becomes easier to see what was empty and what is worth keeping.

Read on the same axis as Rahu, this becomes a line of a person's growth: one end shows what they are pulled to master anew, the other what has already been absorbed to the point of habit and is due to be released. This is why Ketu is called the graha of a path's completion and inner liberation, aimed not at seizing the world but at releasing attachment to it.

In daily practice

As a shadow, harsh graha, Ketu tints a day and its windows with detachment. Such a time favors seeing things through to the end, parting with what is no longer needed, withdrawing and doing inner work, getting to the bottom of hidden causes. It suits loud outward launches, deals and decisions that need clear, reasoned will less well: under Ketu it is easy to miss a detail and give in to doubt.

A node's influence rarely stands alone — it is read together with the Moon's position among the mansions Ketu rules, and with sharp junctions like gandanta at sign transitions. How favorable a Ketu day is for you personally is refined by Tara Bala from your birth nakshatra. Ketu's detachment on a given day is not a cause for alarm but a sign that it is time to let go, finish and clear away, leaving any large new plan for a steadier time.
