A procession of boys lead a herd of white bulls, one ofwhich will be forced up the eight-thousand-footmountain for ritual sacrifice. Preparing for their ascent on Mt. Nyiro, the initiated boysgather at the foot of the mountain carrying long stavesthat they will later fashion into arrows. The boys chant the Labarta, honoring the white bull:“Tell them we have killed the white bull on Mount Nyiro,The white bull that has suckled milk from its mother, Andhas milk in its stomach,Nyiro is blessed where we have killed the bull …” The older boys provide a bass accompanyment, while theyoung initiates voices soar to the heavens. Responding to the emotional intensity of the ceremony,initiates often fall into a trance state called Ndokuna,their bodies rigid as if in an epileptic state.
