Rahu (North Node) in Vedic Astrology

Svarbhanu and the churning of the ocean

The Puranas tell how the devas and asuras churned the ocean of milk for amrita, the nectar of immortality. When Vishnu, as the enchantress Mohini, served it to the gods alone, the asura Svarbhanu slipped into their line disguised as one of them. The Sun and Moon recognised him and called out, and Vishnu's discus took off his head, but the nectar had already passed his throat. The head lived on as Rahu, the body as Ketu, and Rahu still pursues the two luminaries who exposed him, swallowing them at eclipses only to see them slip out from the severed neck.

The image is the key to Rahu's reading: hunger that can taste but never be filled, and a talent for passing as something it is not.

What Rahu signifies

BPHS lists Rahu among the natural malefics and, with Ketu, as the army of the planetary cabinet. Its karaka roles are foreign lands and people, the unconventional, ambition and obsession, sudden events and illusion. BPHS gives it a smoky, blue-black form, a windy constitution and a sharp intelligence, and places it in forests and among people outside settled society. The outsider who reaches for what convention keeps out of reach is the clearest single picture of Rahu.

Dignity: an open question

BPHS states the nodes' dignities only in passing, in its chapter on the effects of Rahu's dasha: Rahu is exalted in Taurus, debilitated in Scorpio, has its mooltrikona in Gemini and owns Aquarius. The same passage records that some sages give it Virgo as its own sign, and many practitioners use Gemini rather than Taurus for exaltation. No degrees are given. BPHS assigns Rahu no gender, element or guna and no directional strength, while Brihat Jataka makes it lord of the south-west.

Shanivat Rahu: borrowing Saturn's relations

BPHS gives the nodes no row in its table of natural friendship. The classical maxim Shanivat Rahu, Kujavat Ketu fills the gap: Rahu acts like Saturn and Ketu like Mars. Read through Saturn, Rahu counts Mercury and Venus as friends, keeps Jupiter neutral and regards the Sun, Moon and Mars as enemies, and that is what this page's table shows. Other conventions exist. A second working rule matters as much: a node delivers much of what its sign lord promises and takes colour from any planet sitting beside it.

Aspect, nakshatras and eighteen years

Every source gives Rahu the 7th-house aspect. Many practitioners add full aspects on the 5th and 9th, as for Jupiter, and opinions differ. Rahu rules Ardra, the storm star of Rudra, in Gemini; Swati, the star of the wind god Vayu, in Libra; and Shatabhisha, the hundred healers of Varuna, in Aquarius. Its Vimshottari mahadasha is eighteen years long; a separate Rahu mahadasha guide on this site covers it.

Transit: the backward axis and eclipse seasons

Rahu spends about eighteen months in a sign, always moving backwards, and completes the circle in about eighteen and a half years, with Ketu exactly opposite. When a new or full Moon falls near the axis an eclipse occurs, which happens in seasons roughly six months apart. Counted from the natal Moon, Phaladeepika makes Rahu's transit favourable in the 3rd, 6th and 11th houses. Eclipse days are traditionally kept for prayer, japa and charity rather than new beginnings.

Remedies associated with Rahu

Rahu has no weekday, so Saturday, Saturn's day, is commonly used for its observances. Durga worship is the traditional devotional route, with the mantra Om Bhraam Bhreem Bhraum Sah Rahave Namah, and with gifts of black or blue cloth, urad, coconut, mustard oil or blankets. Honesty, avoiding intoxicants and refusing shortcuts are counted part of the practice. Hessonite (gomedaka or gomed) is the traditional gem association; wearing it is a personal choice that this page does not recommend, and a gem is no substitute for medical, financial or legal advice.

Rahu and modern work

Tradition connects Rahu with foreign trade and travel, aviation, technology, chemicals and medicines, media, politics and anything new enough to have no rules yet. That is why Rahu in the 3rd, 6th, 10th or 11th house, the growth houses, is often read as ambition with an outlet.

What is Rahu in Vedic astrology?

Rahu is the north node of the Moon, a calculated point where the Moon's orbit crosses the ecliptic. It has no physical body but is counted among the nine grahas because eclipses occur on its axis.

Which day is associated with Rahu?

Rahu owns no weekday. Because it is read like Saturn, Saturday is the day most families use for Rahu observances, along with Durga worship and a Rahu mantra.

What is Rahu's gemstone?

Hessonite, gomed, is the traditional gem association. Wearing it is a personal and traditional choice that this page does not recommend, and it never replaces medical, financial or legal advice.

How long does Rahu stay in one sign?

About eighteen months, moving backwards through the zodiac. Ketu always occupies the opposite sign, so both change sign on the same day.

Is Rahu exalted in Taurus or Gemini?

BPHS gives Taurus for exaltation and Gemini for mooltrikona, while many later practitioners use Gemini as the exaltation sign. Both views are in use, so it is best to know which one a reading follows.

Is Rahu always malefic?

Rahu is a natural malefic, but BPHS describes good results when it is well placed, for example in the 3rd, 10th or 11th house with benefic aspect, or in its exaltation sign. Its sign lord and companions shape it heavily.
