The life actions and decision-making processes of Iban Dayaks depend on divination, augury, and omens. They have several methods to receive omens where omens can be obtained by deliberate seeking or chance encounters. The first method is via dream to receive charms, amulets ( or medicine () and a curse () from any gods, people of Panggau Libau and Gelong, and any spirits or ghosts. The second method is via animal omens (burong laba) which have long-lasting effects such as from deer barking which is quite random in nature. The third method is via bird omens (burong bisa) which have short-term effects that are commonly limited to a certain farming year or a certain activity at hand. The fourth method is via pig liver divination after festival celebration At the end of critical festivals, the divination of the pig liver will be interpreted to forecast the outcome of the future or the luck of the individual who holds the festival. The fifth but not the least method is via or (self-imposed isolation) to receive amulet, curse, medicine, or healing.
