Kaal Sarpa Dosha (KSD) forms when all seven visible planets — Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn — are hemmed in on one side of the Rahu–Ketu axis. The nodes act like the jaws of a serpent, and the chart is said to be "swallowed" between them.
How the dosha actually forms
Rahu and Ketu are always exactly 180° apart. When every other planet falls in the six houses on one side of that axis, the dosha is complete. If even one planet sits outside the axis, it becomes a partial (or "broken") Kaal Sarpa, which is far milder.
The twelve types
KSD is named by the house Rahu occupies — Ananta (Rahu in 1st), Kulika (2nd), Vasuki (3rd), Shankhpal (4th), Padma (5th), Mahapadma (6th), Takshak (7th), Karkotak (8th), Shankhachud (9th), Ghatak (10th), Vishdhar (11th), and Sheshnag (12th). Each colours the effect toward the houses the axis touches.
What it really does
- Delays and sudden reversals rather than permanent denial — themes get postponed, then arrive in a rush.
- Strong results are still possible: many high achievers have KSD, because the concentrated energy can focus ambition.
- The dosha is heavily modified by planetary strength; a well-placed Jupiter or a strong lagna lord softens it considerably.
Remedies that make sense
Classical remedies include worship of Lord Shiva, the Maha Mrityunjaya mantra, and Rahu–Ketu shanti at Trimbakeshwar or Kalahasti. Practically, the more useful "remedy" is disciplined timing — avoid launching major ventures during afflicted Rahu/Ketu dashas and use strong periods instead.
Check your chart honestly
Sivayan detects Kaal Sarpa (full and partial) deterministically from the real Rahu–Ketu positions, and shows which planets, if any, break the axis — so you know whether you have the full dosha or a much milder version, without the fear-selling.
