Avighna Yantra Sutra

Avighna Yantra Sutra is a consecrated thread to be replaced when the existing sutra on Yantra is damaged. The sutra can be removed by untying or burning it. Do not cut it. Dispose of it by burying it under a tree. The soil should be kept wet for a few days. It can also be put in flowing water, such as a river, or a large water body, such as a lake or ocean. It may also be disposed of by tying it to a flowering tree.
