The departure of the soul is not always voluntary. It may be extracted from the body against its will by ghosts, demons, or sorcerers. Hence, when a funeral is passing the house, the Karens tie their children with a special kind of string to a particular part of the house, lest the souls of the children should leave their bodies and go into the corpse which is passing. The children are kept tied in this way until the corpse is out of sight. And after the corpse has been laid in the grave, but before the earth has been shovelled in, the mourners and friends range themselves round the grave, each with a bamboo split lengthwise in one hand and a little stick in the other; each man thrusts his bamboo into the grave, and drawing the stick along the groove of the bamboo points out to his soul that in this way it may easily climb up out of the tomb. While the earth is being shovelled in, the bamboos are kept out of the way, lest the souls should be in them, and so should be inadvertently buried with the earth as it is being thrown into the grave; and when the people leave the spot they carry away the bamboos, begging their souls to come with them. Further, on returning from the grave each Karen provides himself with three little hooks made of branches of trees, and calling his spirit to follow him, at short intervals, as he returns, he makes a motion as if hooking it, and then thrusts the hook into the ground. This is done to prevent the soul of the living from staying behind with the soul of the dead. When the Karo-Bataks have buried somebody and are filling in the grave, a sorceress runs about beating the air with a stick. This she does in order to drive away the souls of the survivors, for if one of these souls happened to slip into the grave and to be covered up with earth, its owner would die. In Uea, one of the Loyalty Islands, the souls of the dead seem to have been credited with the power of stealing the souls of the living. For when a man was sick the soul-doctor would go with a large troop of men and women to the graveyard. Here the men played on flutes and the women whistled softly to lure the soul home. After this had gone on for some time they formed in procession and moved homewards, the flutes playing and the women whistling all the way, while they led back the wandering soul and drove it gently along with open palms. On entering the patient's dwelling they commanded the soul in a loud voice to enter his body.
