Rahu Ketu transit: the 18-month nodal shift
The lunar nodes move differently from every other body: backward, always opposite each other, and slowly. Each nodal shift redraws the axis of desire and release in your chart.
What the nodal transit is
Rahu and Ketu, the north and south lunar nodes, are not physical planets but mathematical points where the Moon's path crosses the ecliptic. They move retrograde, backward through the zodiac, spending roughly eighteen months in each sign, and they are always exactly opposite each other.
So a Rahu Ketu transit always moves a whole axis at once, not a single point.
What it signifies
Rahu is associated with amplification, craving, foreign and unconventional themes, while Ketu is associated with detachment, dissolution and the past. As the nodes transit an axis of houses from your Moon, they tend to intensify and unsettle one area, the Rahu side, while quietly emptying or releasing the opposite, the Ketu side.
Because the shift lasts about eighteen months, it often coincides with longer chapters rather than quick events.
Why it pairs with dasha and Sade Sati
Nodal transits are most meaningful in combination. When a Rahu or Ketu transit lines up with a Rahu or Ketu dasha period, or overlaps Saturn's Sade Sati, the themes reinforce each other and the timing sharpens. Read alone, a nodal transit is a backdrop; read with the dasha, it becomes specific.
This is the multi-layer principle: confluence across transit and dasha is what makes a prediction reliable.
How PI shows the nodal transit
PI computes the live positions of Rahu and Ketu and the houses they occupy from your natal Moon, so you can see exactly which axis is currently activated for you. Combined with your dasha, the AI can discuss the chapter in context rather than offering a one-size nodal forecast.
As with every transit, the geometry is computed first; the interpretation follows from it.
