Rahu and Ketu explained calmly

What Rahu and Ketu are

Rahu and Ketu are not planets you can see. They are two points in the sky, the places where the Moon's path crosses the Sun's apparent path, known as the lunar nodes. Rahu is the north node, where the Moon crosses going north, and Ketu is the south node. They are always exactly opposite each other, 180 degrees apart, which is why they always sit in opposite signs and opposite houses of a chart.

Eclipses happen when the Sun and Moon meet near these points, and that is why old stories link Rahu and Ketu with eclipses. The myth tells of a demon whose head and body were parted: the head became Rahu and the body Ketu. Myths like this are a way of remembering an idea, not facts about the sky.

How they move

In Vedic astrology, Rahu and Ketu move backwards through the zodiac, which is why they are called retrograde. They stay in a sign for about a year and a half, and take about eighteen and a half years to go once around. Both change sign together, Rahu stepping into the sign before the one it left.

What they are traditionally said to stand for

Rahu and Ketu have no body, so tradition treats them as shadow points and gives them symbolic meanings:

• Rahu: hunger, desire, ambition, curiosity, the unusual, the foreign, and things that feel larger than life. It is traditionally compared to a craving that is never quite satisfied.
• Ketu: letting go, detachment, old patterns, intuition and spiritual searching. It is traditionally compared to what has already been finished or understood.
• Together they are seen as an axis: Rahu pulls you towards something, and Ketu invites you to release something. The sign and house they occupy show where.

Rahu and Ketu in your chart

Look at which house Rahu is in. Ketu will be in the house opposite. Tradition reads Rahu's house as an area of strong interest or restlessness, and Ketu's house as an area where you may feel detached, or as if you have been there before. Both also take on the colour of the sign they sit in and of any planet that joins them.

In Vedikshana's planet table they are listed among the nine planets (grahas), each with its sign, house, nakshatra and pada. Without a birth time the houses cannot be worked out, but the signs can.

Rahu and Ketu in the dasha

In the Vimshottari dasha, Rahu's main period (mahadasha) lasts 18 years and Ketu's lasts 7 years. People often feel anxious when a Rahu period begins. Traditionally it is described as a time of ambition, change and sometimes restlessness, and a Ketu period as a time of simplifying and looking inward. Neither is a verdict. Each is a season, and the rest of the chart shapes how it is read.

Fears around Rahu and Ketu, and a calmer way to see them

You may have heard of Kaal Sarp dosha, said to occur when all the other planets lie between Rahu and Ketu. Because the nodes are always opposite each other, the pattern is not unusual, and astrologers disagree about whether it matters at all. Some classical texts do not mention it. It is also often used to sell costly pujas. Please do not buy anything out of fear: nothing in traditional astrology says that you must spend money to be well.

A gentler way is to use Rahu and Ketu as two questions. What am I reaching for, and why? What am I ready to put down? These are good questions in any year, whatever your chart says, and the answers are yours.
