A specially consecrated thread, which when tied around one's wrist, is supportive in fulfilling one's ambitions and removing fear.
Women wear it on the left wrist, men on the right. It must be worn for a minimum of one mandala (48 days). It can be removed by untying or burning it (it should not be cut). The Abhaya sutra should be subsequently buried under a plant near a water body or tied to a flowering/fruit bearing tree or it should be burnt. When it is burnt, you can apply the ashes to your vishudhi chakra (pit of the throat) to the anahata chakra (just below the sternum).
