Bonism is a traditional form of worship involving rituals related to healing and the earth. Some Bon rituals are performed only by certain individuals (Bonpos). Bonpo Karma Wangdi demonstrates a ritual appeasement of Mamo (also known as Lamringbu). His wife and extended family are present because they have not seen this ritual performed for the last 15 years. Mr. Wangdi is the last known Bonpo in Chema village in the Trashi Yangste District of Bhutan. He also belongs to the first generation of Dakpa speakers who started speaking Tshangla in their childhood. Translation into English.
