Odi or oti cult (breaking the human body) is the name given to a form of black magic practiced by the Paraiyans, who, when proficient in it, are believed to be able to render themselves invisible, or assume the form of a bull, cat, or dog. They are supposed to be able to entice pregnant women from their houses at dead of night, to destroy the foetus in the womb, and substitute other substances for it; to bring sickness and death upon people; and so to bewitch people as to transport them from one place to another. A Paraiya who wishes to practice the cult goes to a guru (preceptor), and, falling at his feet, humbly requests that he may be admitted into the mysteries of the art. The master first tries to dissuade him, but the disciple persists in the desire to learn it. He is then tried by various tests as to his fitness. He follows his master to the forests and lonely places at midnight. The master suddenly makes himself invisible, and soon appears before him in the form of a terrible bull, a ferocious dog, or an elephant, when the novice should remain calm and collected. He is also required to pass a night or two in the forest, which, according to his firm belief, is full of strange beings howling horribly. He should remain unmoved. By these and other trials, he is tested as to his fitness. Having passed through the various ordeals, the guru initiates him into the brotherhood by the performance of puja on an auspicious day to his favourite Nili, called also Kallatikode Nili, through whose aid he works his black art. Flesh and liquor are consumed, and the disciple is taught how to prepare pilla thilam and angola thilam, which are the potent medicines for the working of his cult. The chief ingredient in the preparation of pilla thilam, or baby oil, is the sixth or seventh month's foetus of a primipara, who should belong to a caste other than that of the sorcerer. Having satisfied himself that the omens are favourable, he sets out at midnight for the house of the woman selected as his victim, and walks several times round it, waving a cocoanut shell containing a mixture of lime and turmeric water (gurusi), and muttering mantrams to secure the aid of the deity. He also draws yantrams (cabalistic devices) on the ground. The woman is compelled to come out of her house. Even if the door is locked, she will bang her head against it, and force it open. The sorcerer leads her to a retired spot, strips her naked, and tells her to lie flat on the ground. This she does, and a vessel made of a gourd (Lagenaria) is placed close to her vagina. The uterus then contracts, and the foetus emerges. Sometimes, it is said, the uterus is filled with some rubbish, and the woman instantly dies. Care is taken that the foetus does not touch the ground, as the potency of the drug would thereby be ruined. The foetus is cut to pieces, and smoked over a fire. It is then placed in a vessel provided with a few holes, below which is another vessel. The two are placed in a
