Graha
Rahu (Rahu)
राहु
Rahu is the Moon's north node, a shadow planet with no body of its own. It is a point where the Moon's path crosses the Sun's, always exactly opposite Ketu. In the chart Rahu shows hunger: ambition, curiosity and the pull towards the foreign and the new.

What Rahu stands for
Rahu signifies desire and the wish to go beyond what is familiar. It points to foreign lands and foreigners, to technology, to the unconventional and to sudden turns of events. It also signifies illusion, which is why it is the graha of ambition that can run ahead of the facts.
In family matters Rahu is linked to the paternal grandfather. Because it has no sign of its own, it acts through the sign and house it sits in and through the lord of that sign. Rahu magnifies, and the chart shows what it magnifies. Reading it well means looking at the sign lord as much as Rahu.
When Rahu is strong
Texts differ on where Rahu is exalted, some naming Vrishabha and others Mithuna. Whatever the sign, a well placed Rahu gives drive, originality and the courage to leave a beaten path. Foreign connection, work in technology and an unusual rise in life are classical themes.
Rahu also does well in the 3rd, 6th and 11th houses and when it follows a strong sign lord. In such a chart ambition has direction. A person can handle large, unfamiliar systems easily and notice opportunities before others do. Such placements give ambition a clear field to work in.
When Rahu is weak
Here too, texts differ: some name Vrischika as the sign of fall, others Dhanu. A troubled Rahu is read as restless wanting, confusion about goals or a habit of chasing the next thing. It reflects a mind that needs a clear purpose and grounded habits.
Rahu is friendly with Mercury, Venus and Saturn, and it counts the Sun, Moon and Mars as enemies. As with every node, the assessment rests on the house, the sign lord and the planets it joins, and not on one rule taken alone. The classical texts describe these relationships in detail, and astrologers follow them closely.
Traditional remedies
Tradition honours Rahu with the Rahu mantra and with worship of Durga or Shiva. Saturday is often kept for it in some traditions, and the Hanuman Chalisa is also read for steadiness. Clear routines and honest dealings are said to calm what Rahu stirs up.
The traditional donation is a blanket, given to someone who needs it. Serving the poor, sweepers and those who work in the margins is considered service to Rahu's themes. Hessonite is linked with Rahu, but a gemstone should only be worn after a full chart reading.
Questions people ask
Which signs does Rahu rule?
None. Rahu is a shadow planet, one of the Moon's nodes, and texts differ on its exaltation.
Why are Rahu and Ketu always opposite?
They are the two points where the Moon's orbit crosses the Sun's path, so they sit exactly 180 degrees apart. Rahu is the north node and Ketu the south node, and they move backwards through the zodiac together.
How long is the Rahu mahadasha?
In the classical Vimshottari system the Rahu mahadasha lasts 18 years. Its themes of ambition, change and foreign links are shaped by the house Rahu occupies and by the lord of that sign.
