Free Kaal Sarp Yoga (KSY) verdict computed from a real Lahiri-sidereal birth chart. The seven physical planets are tested against the Rahu-Ketu axis to the degree — full, partial or absent — and the named yoga (one of twelve) is identified when the configuration is genuinely present.
Each named yoga corresponds to one of the 12 possible houses Rahu can occupy. The name signals the area of life the configuration most colours — not a fixed outcome.
Rahu in the 1st — colours the self, identity, public-facing personality and physical body.
Rahu in the 2nd — colours speech, family wealth, accumulated resources and food/tastes.
Rahu in the 3rd — colours courage, siblings, short journeys and self-driven initiative.
Rahu in the 4th — colours home, mother, emotional foundations and inner peace.
Rahu in the 5th — colours children, romance, intellect and speculative gain.
Rahu in the 6th — colours health, debts, enemies and daily service/work.
Rahu in the 7th — colours marriage, partnerships, contracts and open opponents.
Rahu in the 8th — colours longevity, transformation, occult, inheritance and joint resources.
Rahu in the 9th — colours dharma, higher learning, the father and long journeys.
Rahu in the 10th — colours career, public reputation, authority and worldly action.
Rahu in the 11th — colours gains, social circle, ambitions and elder siblings.
Rahu in the 12th — colours loss, expenditure, foreign lands, isolation and the inner/spiritual axis.
Kaal Sarp Yoga is the configuration in which all seven physical planets — Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn — fall on one side of the Rahu-Ketu axis (the lunar nodes, which are always 180 degrees apart). Rahu sits at one end of the axis and Ketu at the other; the image is of the seven grahas hemmed between the serpent's head and tail. KSY is descriptive of a karmically concentrated chart pattern; what it actually does in a life depends entirely on the dignity, strength and house lordship of the trapped planets — not on the KSY label by itself.
The 12 named yogas correspond to the 12 possible houses Rahu can occupy: Anant (Rahu in 1st), Kulika (2nd), Vasuki (3rd), Shankhpal (4th), Padma (5th), Mahapadma (6th), Takshak (7th), Karkotak (8th), Shankhachuda (9th), Ghatak (10th), Vishdhar (11th), Sheshnag (12th). The name signals the area of life the configuration most colours — e.g. Anant emphasizes the self and identity, Takshak the marriage and partnership axis, Sheshnag the inner/spiritual axis. The 12 names are a structuring device, not a prescription of fixed outcomes.
Full KSY = every one of the seven planets sits strictly between Rahu and Ketu, with no exception. Partial KSY = one or more planets cross the axis or sit exactly on the node. Many practitioners (including K. N. Rao) hold that partial cases do not count as a true Kaal Sarp at all — if even one planet breaks the hemming, the yoga's classical effect is broken. Our tool reports the verdict honestly: present or not, and full or partial when it is present.
No. KSY is descriptive, not prescriptive. Many high achievers — across business, politics and the arts — carry KSY in their charts. The yoga indicates a karmically concentrated, one-axis pattern; whether it expresses as struggle, breakthrough or both depends on which planets are caught between the nodes, their dignity and house lordship, the natal lagna's strength, and the Rahu/Ketu dasha-antardasha windows. The popular framing of KSY as a guaranteed-misfortune sentence is not supported by either the classical literature or careful chart analysis.
No — and an honest tool has to say so. KSY in its current 12-named-yoga form is a 20th-century formulation popularized chiefly by modern authors such as Bepin Behari (Esoteric Principles of Vedic Astrology) and discussed with clear practical limits by K. N. Rao. It does not appear as a verse in BPHS, Phaladeepika or Saravali. We treat the yoga on its modern terms and cite the modern source rather than inventing a classical reference. BPHS is referenced here only as the background for Rahu/Ketu's nature and house results, not as the source of KSY itself.
Traditional remedies include Nag Panchami observance, the Rahu and Ketu beej mantras, recitation of the Sarpa Sukta or Maha Mrityunjaya, and pilgrimage-based pujas at Trimbakeshwar (Nashik) or Kalahasti. Even on the modern KSY framework these are warranted only when (a) the yoga is genuinely full, not partial, and (b) the Rahu or Ketu dasha-antardasha is currently active or imminent. Most charts told they have KSY are partial cases, where no remedy is honestly warranted. An astrologer who recommends a costly puja for a partial KSY without that test is over-selling the diagnosis.
