It is thought that during the hunt only those people who have been selected by the spirit of the sea could kill the whale. The hunter has to please the killed whale: it must be treated as a guest. Just like a polite host does not leave a recently arrived dear guest alone, thus similarly, the killed whale should not be left alone by the host (i.e. by the hunter who has killed it). Like a guest, it should not get hurt or feel sad. It must be entertained (e.g. by drum music, good foods). On the next whale migration (whales migrate twice a year, in spring to the north and in the autumn back), the previously killed whale is sent off back to the sea in the course of a farewell ritual. If the killed whale was pleased to (during its being a guest for a half year), then it can be hoped that it will return later, too: thus, also the future whale hunts will succeed.
