Up to this point only those spirits who attend the ceremony with friendly intent have been provided for, but the Tinguian realize that there are others who must be kept at a distance or at least be compelled to leave the body unharmed. The first of these evil beings to be guarded against is Kadongáyan, [91] who in former times used to attend each funeral and amuse himself by sliting the mouth of the corpse, so that it extended from ear to ear. Through the friendly instruction of Kaboniyan it was learned that, if a live chicken, with its mouth split down to its throat, were fastened to the door of the house, its suffering would be noticed by the evil spirit, who, fearing similar treatment, would not attempt to enter the dwelling. [92] The spirit Ibwa is also much feared. [93] Long ago he used to mingle with the people in human form, without harming them, but the thoughtless act of a mourner started him on the evil course he has since pursued. In those times, it is said, the corpse was kept in the dwelling seven days; and, as the body decomposed, the liquid which came from it was caught in dishes, and was placed in the grave. On the occasion referred to, he was handed a cup of the "lard" to drink. He immediately acquired a great liking for this disgusting dish, and frequently even devoured the body as well. Since he fears iron, it is possible to drive him away by using metal weapons. It is also necessary to guard the grave against him and the spirit Selday, who demands blood or the corpse.
