Definition: When all 7 planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn) fall between Rahu and Ketu in the birth chart, Kaal Sarp Dosha is formed.
12 Types: Named after serpents in Hindu mythology — each type corresponds to a Rahu house position and brings different life challenges.
Effect: Delays, obstacles, and sudden reversals in life — especially in the areas ruled by the houses involved. Not always negative; many famous people have this dosha.
