Armand Camhol discusses the significance of narra wood, locally known as haidu, considered to be one of the strongest and most valued materials for creating bulul sculptures. Camhol explains the cultural importance of commissioning these carvings, a process that traditionally involves substantial offerings, such as the butchering of multiple pigs and the sharing of rice wine. He also highlights the communal aspect of the ritual, with participants being offered food and drink throughout the ceremony.
