The Kaal Sarp Yog Yantra is also called Naag-pash Yantra. Worship of the energised Kaal Sarp Yog Yantra reduces the ill-effects of the Kaal Sarp Yoga. People having Kaal Sarp Dosh shall perform puja on Naag-Panchmi as well as establish energised Kaal Sarp Yog Yantra in their house to protect themselves from the evil effect of this yoga.
