[The next chapter will contain a number of vampire stories which, in some respects, resemble these tales of homicidal corpses. But most of them belong, I think, to a separate group, due to a different myth or superstition from that which has given rise to such tales as those quoted above. The vampire is actuated by a thirst which can be quenched only by blood, and which impels it to go forth from the grave and destroy. But the enchanted corpses which rise at midnight, and attempt to rend their watchers, appear to owe their ferocity to demoniacal possession. After the death of a witch her body is liable, says popular tradition, to be tenanted by a devil (as may be seen from No. iii.), and to corpses thus possessed have been attributed by the storytellers the terrible deeds which Indian tales relate of Rákshasas and other evil spirits. Thus in the story of Nischayadatta, in the seventh book of the "Kathásaritságara," the hero and the four pilgrims, his companions, have to pass a night in a deserted temple of Siva. It is haunted by a _Yakshini_, a female demon, who turns men by spells into brutes, and then eats them; so they sit watching and praying beside a fire round which they have traced a circle of ashes. At midnight the demon-enchantress arrives, dancing and "blowing on a flute made of a dead man's bone." Fixing her eyes on one of the pilgrims, she mutters a spell, accompanied by a wild dance. Out of the head of the doomed man grows a horn; he loses all command over himself, leaps up, and dances into the flames. The _Yakshini_ seizes his half-burnt corpse and devours it. Then she treats the second and the third pilgrim in the same way. But just as she is turning to the fourth, she lays her flute on the ground. In an instant the hero seizes it, and begins to blow it and to dance wildly around the _Yakshini_, fixing his eyes upon her and applying to her the words of her own spell. Deprived by it of all power, she submits, and from that time forward renders the hero good service.[368]]
