Ai.--In order that a person after death may gain possession of the spirits of the men or wild animals he has killed here below, it is necessary for him to sacrifice a mithan, goat, or pig. This is called "Ai." After this feast, before the skull can be placed in the front verandah, a religious ceremony has to be performed by the puithiam. This is called "Sa-lu-an-chhuang"--i.e., "Hoist the head of the wild animal." A small white fowl is given to him and the skull of the animal is placed in front of him. He then takes some zu in his mouth and spits it out over the skull, and, after muttering a charm in so low a tone that no one can hear him, he strikes the skull with the head of the chicken. If some of the feathers stick on the skull it is very lucky. After this the skull can be put up. As is stated further on, the Lushais believe that the spirit of a dead man cannot pass to Mi-thi-khua unless some animals are killed. These have to be provided by the heir, and no greater objection can be urged against a claim to inherit than a failure to provide the funeral sacrifice. This explains the reason of the Ai ceremony; the performer thereby enables the spirit of the dead animal to pass to Mi-thi-khua and in return acquires power over it. No Ai has to be performed for tame animals, presumably because they are the property of the slayer already. The word "Ai" has many meanings--among them are "to fascinate," "to obtain power over"; and there is also a plant of that name, which in one of the folk tales is said to have the magical property of driving away any evil spirit at which it is pointed. The Ai of a man requires the sacrifice of a mithan and a small pig. If an enemy is killed and no Ai performed the slayer is very likely to go mad. If you perform the Ai you can take your enemy with you (as a slave) when you die; if you do not perform the Ai you cannot do so, and the spirit of your deceased enemy will haunt you in this life.
