In South-Western Tibet the _Hunyas_ (Tibetans) have the same strange notions on transmigration of evil spirits that are common to the Shokas. For instance, if a man falls ill, they maintain that the only remedy is to drive away the evil spirit which has entered his body. Now, according to Tibetan and Shoka ideas, evil spirits always enter a living body to satisfy their craving for blood: therefore, to please the spirit and decoy him away, if the illness be slight, a small animal such as a dog or a bird is brought and placed close by the patient; if the illness be grave, a sheep is produced and exorcisms are made in the following fashion. A bowl of water is whirled three or four times over the sick man's head, and then again over the animal selected, upon whose head it is poured. These circles, described with certain mystic words, have the power of drawing the spirit out of its first quarters and causing it to enter the brain of the second victim, upon whose skull the water is poured to prevent its returning back. "Of course," said my informer with an air of great gravity, "if you can give the evil spirit a present in the shape of a living being that will satisfy him, he will depart quite happy." If the illness is slight, it means that the spirit is not much out of temper, and a small present is enough to satisfy him, but if the disease is serious, nothing less than a sheep or even a yak will be sufficient. As soon as the spirit has changed his temporary abode the animal is quickly dragged away to a crossing of four roads, and if there are no roads a cross is previously drawn on the ground, where a grave for the animal is dug, into which it is mercilessly thrown and buried alive. The spirit, unable to make a rapid escape, remains to suck the blood of his last victim, and in the meantime the sick man, deprived of the company of his ethereal and unwelcome guest, has time to make a speedy recovery. When a smaller animal is used, such as a dog or a bird, and when the patient complains of more than one ailment, the poor beast, having been conveyed to the crossing of four roads, is suddenly seized and brutally torn into four parts, which are flung in four different directions, the idea being that, wherever there may be spirits waiting for blood, they will get their share and depart happy. After their craving is satisfied, the evil spirits are not very particular whether the blood is human or not. In Shoka land especially, branches with thorns and small flying prayers are placed on each road to prevent their immediate return. These are said to be insuperable barriers to the evil spirits. [Illustration: BRANCH WITH THORNS TO PREVENT RETURN OF EVIL SPIRITS] When a patient completely recovers, the Lamas naturally obtain money for the exorcisms which have expelled the illness, and they never fail to impress upon the people the extraordinary powers they possess over the much-dreaded demons.
