Kalsarp Dosh, which is sometimes spelt Kaal Sarp Dosha, is a concept in Hindu astrology that pertains to the placement of planets in a person's birth chart (or horoscope). This theory holds that a Kalsarp Dosh is produced when all seven planets—the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn—are positioned between the dark planets Rahu and Ketu.

Rahu and Ketu are seen as unfavourable or harmful forces, and it is thought that their existence will provide difficulties and hurdles in the life of an individual. It is frequently seen as an unfavourable astrological combination, and some people think it may result in a variety of problems, including financial hardships, health challenges, relationship issues, and professional failures.

In order to lessen the symptoms of Kalsarp Dosh, believers may turn to rituals and cures. To counteract the negative impacts and increase the good energy in the person's life, astrologers may recommend certain prayers, gemstones, or rituals.

It's important to remember that Kalsarp Dosh concept is a component of Hindu astrology and is not generally acknowledged or supported by science. Its relevance varies among astrologers, and various astrologers may interpret and evaluate its consequences differently.
