HORN / ZART
Kangling, literally translated as "leg" (kang) "flute" (ling), is the Tibetan name for a trumpet or horn made out of a human tibia or femur, used in Tibetan Buddhism for various chöd rituals as well as funerals performed by a chöpa. T The kangling may also be made out of wood, or in this case, brass.
The kangling should only be used in chöd rituals performed outdoors with the chöd damaru and bell. In Tantric chöd practice, the practitioner, motivated by compassion, plays the kangling as a gesture of fearlessness, to summon hungry spirits and demons so that she or he may satisfy their hunger and thereby relieve their sufferings. It is also played as a way of "cutting off of the ego."
