Rice agriculture in the Ifugao mountainous area of fertile land is the primary reason for their physical survival. This fact in anyway obliges the Ifugao people to invent a preventive or defensive instrument to protect their environs and its agricultural produce. Thus, the creation of Bul-ul, the Rice God. A Bul-ul is a carved wooden figure used to guard the rice crop by the Ifugao people of northern Luzon. The sculptures are highly stylized representations of ancestors and are thought to gain power from the presence of the ancestral spirit.
