When animals or human beings serve as the sacrificial gift,
the shedding of blood may become an essential part of the sacrificial action.
Thus ritual slaying makes its cultivators and herders.
(The practice is generally not found in hunting cultures, where a small but symbolically important part of the animal slain during the hunt is offered: thus the slaying is not part of the sacrificial a but precedes it. The slaying by the Ainu of a bear raised for the purpose is perhaps not really a sacrifice but a dismissal" rite.)
