What Kaal Sarp Dosha is
Rahu and Ketu are the lunar nodes, always exactly opposite each other in the zodiac. Kaal Sarp Dosha is said to form when all seven planets from the Sun to Saturn lie on one side of the Rahu-Ketu axis, as if enclosed within the coils of a serpent. When one or two planets fall outside the axis, the condition is called partial Kaal Sarp.
It is worth knowing that the name is not found in the main Parashari texts such as Brihat Parashara Hora Shastra; it appears in later tradition. Some respected astrologers therefore give it little weight, while others consider it significant. Both views are part of the living tradition.
