Most of what is chanted consists of meaningless sounds, it being supposed that what is not understood by man is intelligible to the spirits. But some parts of it can be understood by the careful listener. The witch doctors call upon the sickness to be off to the ends of the earth and return to the unseen regions from whence it came. They invoke the aid of spirits, as well as their own ancestors, and spin out the invocation to last till early morning. Then they rush round the _Pagar Api_ as hard as they can go, still singing their incantation. One of their number suddenly falls on the floor and lies motionless. The others sit down round him. He is covered over with a blanket, and all wait, while his spirit is supposed to hurry away to the other world to find the wandering soul and bring it back. Presently he revives, and looks vacantly round like a man just waking out of sleep. Then he raises his right hand clenched as if holding something. That hand contains the soul, and he proceeds to the patient, and solemnly returns it to the body of the sick man through the crown of his head. This "catching of the soul" is the great end to which all that has preceded leads up. One more thing must be done to complete the cure. A live fowl must be waved over the patient, and as he does so, the leader sings a special invocation of great length. The animal is afterwards killed as an offering to the spirits, and eaten by the _Manangs_. The witch doctor is supposed to be called to his profession by a revelation made to him in a dream by some spirit. He therefore claims to have a familiar spirit, whom he can call to his aid when necessary. He must also commit to memory a certain amount of Dyak incantations to take part in the ceremonies in company with other _Manangs_. In addition to this, before he can accomplish the more important feats such as pretending to catch the soul of a sick man, he must be initiated by other witch doctors. There are three different grades of _Manangs_, and the higher the grade is, the larger the fees the aspirant has to pay the other witch doctors. There are some differences in the ceremonies connected with the admission into each of these three grades, but in all of them the aspirant sits in the verandah of the Dyak house, and a number of witch doctors walk round him singing incantations during the whole night. The other _Manangs_ pretend to endow him with mysterious powers, and to make him able to "touch" the maladies of the body, and also to see the soul wherever it may be wandering.
