Dharani cord
The dharani cord (Tib. གཟུངས་ཐག, Wyl. gzungs thag) is a string of five-colored threads attached to the mandala on one end, and to a vajra on the other. During a drupchen, the vajra is held by the vajra king (the master presiding over the practice) during the mantra recitation, and the rest of the time by the practitioners holding the continuous recitation of the mantra. The cord links together the front and self-visualizations.
