Phi ka (¼Õ¡Ð)
            The Chiengmai people say that the phi ka is a phi in human* form. A person who is a phi ka has a queer habit different from that of ordinary people and his eyes are always restless with furtive glances. This phi is voracious like the phi krasu hence its name phi ka. I am told that the word "ka" and "chakla" (¨Ð¡ÅÐ) which mono voracious or greedy are one and the same word. The former is a shortened form of the latter. A phi ka will get, into any person, no doubt to eat the entrails like the phi krasu. The obsessed person will suffer acute pains. In such a case a sorcerer or medicine man called in Thai, "maw phi" (ËÁͼÕ) or phi doctor is called in for help. In the Northeast a "maw phi" is called "maw devada", or devada doctor, Do doubt to avoid ambiguity of meaning in the word "Phi" which means either a god or an evil spirit. A maw phi is also a man who keeps phi for his evil purposes.
            The doctor will drive out the phi ka by beating hard on the patient with his magic rod, or he may use a magic knife called "mit maw" (ÁÕ´ËÁÍ) or doctor's knife.     Or lie may use a magic elephant's tooth, pricking in various places on the person's body.Every time he beats on the patient with his magic rod or pricks with his knife or other instrument, the person will cry in the name of the phi ka for quarter. He will say, for instance, "Ouch! Ouch! I fear you and will go out now. Don't whip me further. " And in answer to the doctor's question, the phi ka will reply that he is a person named so and so and lives in such and such a village. If the phi ka leaves the body, the, obsessed person will regain his normal state and suffer no physical pains from the whipping or pricking by the doctor. Now the person who is the guilty phi ka, if traced be made to his house, will be found to suffer from such whipping or pricking as was administered by the doctor to the obsessed person. As to what punishment is due to the man who is found to be a phi ka, my informant knows nothing as this story comes from a " tradition, which does not explain the punishment. But the "phi POP Northeast can supply a clue; for the phi pop and the phi clearly the same kind of phi with different names only.
