Kalsarp Dosha Nivaran is formed when all the planets are situated between Rahu & Ketu. When all the planets are hemmed between Rahu and Ketu i.e., the moon's north node and the moon's south node Kal Sarp Yoga is formed. At times a few planets are outside the circumference or reach of rahu and ketu. This yog brings negative thoughts in our mind and also creates fear in our mind. A yantra is made by man and it has to be energized through mantras from the Vedas so that it helps the person connect with the higher power. This process of energizing the yantra is undertaken by priests. The process of placing this energized yantra in homes is also important and must be followed in a right manner. There are 12 Types of Kalsarp Pooja.
