[Sidenote: Beliefs of the Bukaua concerning the souls of the dead. Sickness and disease attributed to ghostly agency.]
The Bukaua have a firm belief in the existence of the human soul after death. They think that a man's soul can even quit his body temporarily in his lifetime during sleep or a swoon, and that in its disembodied state it can appear to people at a distance; but such apparitions are regarded as omens of approaching death, when the soul will depart for good and all. The soul of a dead man is called a _balum_. The spirits of the departed are believed to be generally mischievous and spiteful to the living, but they can be appeased by sacrifice, and other measures can be taken to avert their dangerous influence.[418] They are very touchy, and if they imagine that they are not honoured enough by their kinsfolk, and that the offerings made to them are insufficient, they will avenge the slight by visiting their disrespectful and stingy relatives with sickness and disease. Among the maladies which the natives ascribe to the anger of ghosts are epilepsy, fainting fits, and wasting decline.[419] When a man suffers from a sore which he believes to have been inflicted on him by a ghost, he will take a stone from the fence of the grave and heat it in the fire, saying: "Father, see, thou hast gone, I am left, I must till the land in thy stead and care for my brothers and sisters. Do me good again." Then he dips the hot stone in a puddle on the grave, and holds his sore in the steam which rises from it. His pain is eased thereby and he explains the alleviation which he feels by saying, "The spirit of the dead man has eaten up the wound."[420]
[Sidenote: Sickness and death often ascribed by the Bukaua to sorcery.]
But like most savages the Bukaua attribute many illnesses and many deaths not to the wrath of ghosts but to the malignant arts of sorcerers; and in such cases they usually endeavour by means of divination to ascertain the culprit and to avenge the death of their friend by taking the life of his imaginary murderer.[421] If they fail to exact vengeance, the ghost is believed to be very angry, and they must be on their guard against him. He may meet them anywhere, but is especially apt to dog the footsteps of the sorcerer who killed him. Hence when on the occasion of a great feast the sorcerer comes to the village of his victim, the surviving relatives of the dead man are at particular pains to protect themselves and their property against the insidious attacks of the prowling ghost. For this purpose they bury a creeper with white blossoms in the path leading to the village; the ghost is thought to be filled with fear at the sight of it and to turn back, leaving his kinsfolk, their dogs, and pigs in peace.[422]
