Rahu and Ketu: Karmic Path to Life Purpose

Rahu and Ketu: Karmic Path to Life Purpose

In Human Design, the lunar nodes—Rahu and Ketu—are not mystical curiosities or generic astrological shorthand. They are precise points in your bodygraph that reveal the exact trajectory of your life. Where you have been. Where you are going. And the specific evolutionary current flowing through you.

If your Strategy is how you move, and your Authority is how you decide, Rahu and Ketu show you the direction itself. They are the riverbed. Your life is the water.

How the Nodes Are Calculated

Rahu and Ketu sit in your Design (unconscious, red) and Personality (conscious, black) charts respectively.

The North Node—Rahu—is determined by the position of the Sun 88 days before you were born. The South Node—Ketu—is the Sun's position 88 days after your birth. They are always exactly opposite each other in the mandala, 180 degrees apart, creating one continuous axis of evolution.

Each node falls within a specific I Ching gate. Together, those two opposite gates form a single channel—the electromagnetic bridge that carries the karmic theme of your incarnation. This channel is the spine of your evolutionary journey in this life. It is, in fact, the same channel your Sun crosses from Personality to Design, the very axis your Incarnation Cross is built upon. The nodes are not an addition to your design. They are the backbone of it.

Ketu: The Tail of the Dragon

Ketu is your South Node. It belongs to your Design—your body, your automatic patterns, the deep operating system you arrived with.

Ketu is what you already know. The gifts you brought in. The skills that come too easily to be noticed. The conditioning that shaped you in deep patterns—ancestral, familial, sometimes carried from experiences far older than this lifetime.

Because Ketu lives in the Design, it is fixed. You cannot grow it through effort. It is the foundation. When transits activate your Ketu gate, you will feel a strange familiarity, a pull backward, a sense of "I have done this before."

The trap of Ketu is comfort. It is tempting to build your life around what you already know, what you have mastered, what feels natural. But Ketu is the tail, not the head. It is what you are moving away from, not what you are moving toward.

Rahu: The Head of the Dragon

Rahu is your North Node. It lives in your Personality—the conscious, aware, magnetic part of you that the world can see.

Rahu is where you are going. It is the unfamiliar territory your soul is hungry for. The strange interests that do not fit your conditioning. The desires that seem inconsistent with your past.

Unlike Ketu, Rahu can be developed. It is the evolutionary direction you are here to embody. When you live in alignment with your Rahu, life feels meaningful even when it is uncomfortable. When you live against it, even success feels hollow.

Rahu is not a destination you arrive at. It is a direction you orient toward. The goal is not to master it and stop. The goal is to keep facing it, to let it pull you forward through the rest of your life.

The Trajectory Between Them

The channel formed by your Rahu and Ketu gates is a single unit. One end is conscious and magnetic (Rahu). The other is unconscious and fixed (Ketu). Energy flows between them constantly, like breath.

The gates of the channel describe both the challenge and the gift. Your Ketu gate is the well you draw from. Your Rahu gate is the river you pour it into. The channel names the specific theme—awareness, transformation, listening, rhythm, survival, love—that defines the work.

Your Incarnation Cross is built around this axis. The four gates of your Sun and Earth in both Personality and Design—each tied to the nodal channel—form the four-fold purpose of your life. Rahu and Ketu are not just inputs to the cross. They are the directional current the cross is designed to express.

Environment and Direction

Here is where environment becomes essential.

Ketu environments feel like home. The people who knew the old you. The work that uses only the old skills. The places that confirm the familiar story. Staying in a Ketu environment is easy and deeply unsatisfying.

Rahu environments feel foreign at first. The people who only know the current version of you. The work that demands growth. The places that invite you to become more than you have been.

Living your trajectory means arranging your environment to support the direction of Rahu, not the comfort of Ketu. This is not about abandoning your gifts. Your Ketu gifts are the foundation of everything you build. But they are the foundation, not the building.

When a planet transits your Ketu gate, the past comes calling. People, memories, old ways of being. The work is to honor what surfaces without reorganizing your life around it. When a planet transits your Rahu gate, the future is knocking. New opportunities, strange synchronicities, unfamiliar faces. The work is to say yes before you are ready.

Living the Arc

Rahu and Ketu are not a test you pass or fail. They are the shape of your life in this body. Ketu is the depth of the well. Rahu is the height of the sky. The water between them is every day you are alive.

Your work is to keep moving along the axis. To let the past inform you without defining you. To let the future call you without paralyzing you. To build an environment that supports the direction of your evolution rather than the comfort of your conditioning.

This is what it means to live a directed life. Not a life of accident, not a life of pure past, but a life with a trajectory—yours, specifically, with your gates, your channel, your cross, your Rahu ahead and your Ketu behind.

The dragon is already moving. Your job is to face the right way.
