The earthly authority, whose words and actions should be cleaved to both in life (agriculture) and death (funerals), is called to minaa (an aluk priest). Aluk is not just a belief system; it is a combination of law, religion, and habit. Aluk governs social life, agricultural practices, and ancestral rituals.
