Kaal Sarp Dosh Puja is a powerful remedial ritual in Hindu astrology to reduce the malefic effects of Kaal Sarp Dosh in a person’s horoscope. This dosh occurs when all seven planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn) are positioned between Rahu and Ketu, forming a “snake-like” structure — where Rahu is the serpent's head and Ketu is the tail.
