Who is Rahu
Rahu is one of the nine celestial bodies (Navagraha) in Hindu astrology, representing the ascending lunar node. Unlike physical planets, Rahu is a shadowy, invisible entity that exerts powerful karmic influences. Its earliest mention appears in the Rigveda (1.32.4) as Svarbhānu, a demon who obscures the sun, later beheaded by Indra. The Puranic origin is narrated in the Samudra Manthan (churning of the ocean) episode from the Mahabharata (Vana Parva) and the Bhagavata Purana (8.9). During the churning, the asura Svarbhānu disguised himself among the devas to drink the nectar of immortality.
Surya and Chandra alerted Vishnu, who severed his head with the Sudarshana Chakra. However, having already consumed the nectar, both head and tail became immortal—the head as Rahu and the tail as Ketu. Since then, Rahu eternally pursues the sun and moon, causing eclipses when he swallows them (Bhagavata Purana 5.24.2). Iconographically, Rahu is depicted as a dark, severed head riding a chariot drawn by eight black horses, often holding a sword or shield, and shown swallowing the sun or moon. Symbolically, Rahu represents obsession, mystery, sudden upheavals, and karmic patterns that drive worldly desires and spiritual growth.
In Vedic astrology, Rahu's placement in a birth chart indicates areas of intense focus, illusion, and unexpected events. Regional worship includes Rahu Puja during eclipses and on Saturdays, especially in South India, where Rahu is propitiated for relief from doshas (afflictions). The Skanda Purana describes Rahu as a graha that influences material success and occult sciences. In Hindu cosmology, Rahu is considered a shadow planet (chhaya graha) with no physical form, yet its gravitational pull on human destiny is profound. The Jyotisha Shastra details Rahu's transits and their effects on worldly affairs.
Rahu's association with the headless form signifies the eternal hunger for unfulfilled desires, and its worship is believed to mitigate the malefic effects of karmic debts.
Roots of the name
The name Rāhu derives from the Sanskrit root 'rah' meaning 'to abandon' or 'to leave', signifying the severed head that was separated from its body. In the Rigveda (1.32.4), the entity is called Svarbhānu, 'the splendor of the sun', later identified with Rahu.
The term 'Rahu' appears in the Atharvaveda (19.9.7) as a demon causing eclipses. Regional variants include 'Rahu' in Hindi, 'Rāhu' in Tamil, and 'Rahu' in Telugu.
The name is also linked to 'rahu' meaning 'to seize', reflecting its role in eclipses. In Puranic literature, Rahu is synonymous with the ascending lunar node, while Ketu represents the descending node.
The etymology underscores its nature as a shadowy, karmic entity.
Where the deity first appears
Rahu's earliest trace appears in the Rigveda (1.32.4) as Svarbhānu, a demon who strikes the sun with darkness, later freed by Atri's sons (Rigveda 5.40.5-9). The Atharvaveda (19.9.7) mentions Rahu as a demon causing eclipses.
The Mahabharata (Vana Parva, chapters 100-102) narrates the Samudra Manthan where Svarbhānu drinks amrita and is beheaded by Vishnu, becoming Rahu and Ketu. The Bhagavata Purana (8.9.25-29) elaborates this myth, establishing Rahu as a graha.
The Puranas, especially the Skanda Purana, elevate Rahu to a navagraha, influencing astrology. The Jyotisha Shastra, such as the Brihat Parashara Hora Shastra, details Rahu's astrological effects.
Thus, Rahu evolves from a Vedic demon to a Puranic planetary deity.

Rahu is depicted as a dark, severed head with a fierce expression, often wearing a crown and adorned with blue garments and sandal paste. He has two arms holding a sword and shield, or a winnow (soorpa) and a spear.
His complexion is smoky or black, and he is sometimes shown with a serpentine body or riding a chariot drawn by eight black horses.

The dhyana-shloka describes him as wearing blue silk, a crown, and holding a winnow, granting protection. Regional variations include the depiction of Rahu with a lion-like face in some traditions.
The Shilpa-shastra texts prescribe his iconography for temple niches, often as part of the Navagraha panel. In some representations, Rahu is shown with a half-body, emphasizing his severed nature.
Philosophical interpretations
In Advaita Vedanta, Rahu represents the illusory power (maya) that veils the true self, causing attachment to worldly desires. Vishishtadvaita views Rahu as a karmic agent that dispenses the fruits of past actions, influencing the soul's journey. Dvaita philosophy sees Rahu as a distinct entity under Vishnu's control, affecting material existence.
In Shakta traditions, Rahu is associated with the goddess's power to create and dissolve illusions. Tantric texts consider Rahu a guardian of esoteric knowledge and a deity to be propitiated for siddhis (supernatural powers). In Vaishnava thought, Rahu is a servant of Vishnu, executing divine will through eclipses and astrological influences.
The Jyotisha Shastra describes Rahu as a shadow planet (chhaya graha) that intensifies desires and karmic patterns. Commentators like Varahamihira (Brihat Samhita) detail Rahu's effects on human destiny, emphasizing its role in sudden changes and spiritual growth. Rahu's headless form symbolizes the eternal hunger for unfulfilled desires, and its worship is believed to mitigate malefic influences.
Sacred utterances
Vedic remediation guidance
- Rahu mahadasha challenges
- Foreign-land issues
- Sudden upheavals
- Anxiety
Rahu, the disembodied head of Svarbhānu, is worshipped as a shadow-graha that grants boons when propitiated, yet brings upheaval when afflicted. Worship of Rahu is most recommended when Rahu occupies a kendra or trikona in conjunction with a weak or retrograde Saturn, during Rahu mahadasha or antardasha, when Rahu transits Ardra, Swati, or Shatabhisha nakshatra, or when Saturn is afflicted in the 8th house or during Sade Sati. The concrete remedial pattern involves reciting the Rahu Beeja Mantra ("Om Bhram Bhreem Bhroum Sah Rahave Namah") 108 times on a Saturday, using a japa mala of smoke-colored beads, preferably at noon. Complementary observances include fasting from grains, offering black sesame seeds, mustard oil, or blue lotus flowers to a Rahu yantra, and donating iron or black cloth to a south-facing temple. This practice pacifies Rahu's malefic influence, alleviating anxiety, foreign-land issues, and sudden upheavals.
