Ketu (mythology)

Ketu (Sanskrit: केतु, IAST: Ketú) () is the descending (i.e. 'south') lunar node in Vedic, or Hindu astrology.^[2][3][4] Personified as a deity, Rahu (, the ascending (i.e. 'north') lunar node) and Ketu are considered to be the two halves of the immortal asura (demon) Svarbhanu, who was beheaded by the god Vishnu.

As per Vedic astrology, Rahu and Ketu have an orbital cycle of 18 years and are always 180 degrees from each other orbitally (as well as in the birth charts). This coincides with the precessional orbit of moon or the ~18-year rotational cycle of the lunar ascending and descending nodes on the earth's ecliptic plane. Ketu rules the Scorpio zodiac sign together with Mangala (traditional ruling planet; Mars in Western astrology).

Astronomically, Rahu and Ketu denote the points of intersection of the paths of Surya (the Sun) and Chandra (the Moon) as they move on the celestial sphere, and do not correspond to a physical planet.^[5] Rahu and Ketu are respectively names of the north and the south lunar nodes. Eclipses occur when the Sun and the Moon are at one of these points, giving rise to the myth that the two are being swallowed by the snake. Ketu is believed to be responsible for causing the lunar eclipse.^[5]

In Hindu astrology, Ketu represents karmic collections both good and bad, as well as spirituality and supernatural influences. Ketu signifies the spiritual process of the refinement of materialisation to the spirit and is considered both malefic and benefic: this process causes sorrow and loss, and yet at the same time turns the individual to God. In other words, it causes material loss in order to force a more spiritual outlook in the person. Ketu is a karaka or indicator of intelligence, wisdom, non-attachment, fantasy, penetrating insight, derangement, and psychic abilities. Ketu is believed to bring prosperity to the devotee's family, and removes the effects of snakebite and illness arising out of poisons. He grants good health, wealth and cattle to his devotees. Ketu is the lord of three nakshatras or lunar mansions: Ashvini, Magha and Mula.

Ketu is considered responsible for moksha, sannyasa, self-realization, gnana, a wavering nature, restlessness, the endocrine system and slender physique.

The people who come under the influence of Ketu can achieve great heights, most of them spiritual.

Rahu, being a karmic planet, shows the necessity and urge to work on a specific area of life where there had been ignorance in the past life. To balance the apparent dissatisfaction one has to go that extra mile to gain a satisfactory settlement in the present lifetime. Rahu can remove all negative qualities of every planet, while Ketu can emphasise every positive quality of the planet.

Ruler: According to the popular astrology text Brihat Parashara Hora Shastra (BPHS), if looking for solutions regarding Ketu, consider working with mantra of Ganesha & Matsya.

Exaltation and Debilitation: This has been a debatable point in astrology, as per BPHS Ketu is exalted in the sign of Scorpio and debilitated in Taurus. However, many astrologers have disputed this and most modern astrologers now seem to agree that Ketu is exalted in Sagittarius and debilitated in Gemini. This stands to logic as Ketu is a torso and a prominent part of Sagittarius is a big horse torso attached to a male upper body.

Negative Significations: Ketu is considered malefic and has been mostly associated with negative things. Most people consider it a difficult planet as it manifests as obstacles on the material plane. However Lord Ganesha mantras can help remedy those issues because Ganesha is the presiding deity of Ketu. Ketu often brings a sense of complete detachment, losses, mindlessness, wandering, and confusion in one's life.

Positive Significations: There is a much deeper side to Ketu and it has been called the most spiritual of all planets. Ketu has been considered the planet of enlightenment and liberation. It is the one who has “lost his head (worldly senses = Tattva (Ayyavazhi))”, being a personification of renunciation (torso without a head who needs nothing). Ketu is the ascetic that wants to go beyond the mundane life and achieve the final liberation.

Friendly Planets: Ketu is a friend of Mercury (Budha), Venus (Shukra), and Saturn (Shani); neutral with Jupiter (Brihaspati) and acrimonious with the Sun (Surya), Moon (Chandra), and Mars (Mangala).
