A Pulluvan and his wife preside at the ceremony called Pāmban Tullal to propitiate the snake gods of the nāgāttān kāvus, or serpent shrines. For this, a pandal (booth) is erected by driving four posts into the ground, and putting over them a silk or cotton canopy. A hideous figure of a huge snake is made on the floor with powders of five colours. Five colours are essential, as they are visible on the necks of snakes. Rice is scattered over the floor. Worship is performed to Ganēsa, and cocoanuts and rice are offered. Incense is burnt, and a lamp placed on a plate. The members of the family go round the booth, and the woman, from whom the devil has to be cast out, bathes, and takes her seat on the western side, holding a bunch of palm flowers. The Pulluvan and his wife begin the music, vocal and instrumental, the woman keeping time with the potdrum by striking on a metal vessel. As they sing songs in honour of the snake deity, the young female members of the family, who have been purified by a bath, and are seated, begin to quiver, sway their heads to and fro in time with the music, and the tresses of their hair are let loose. In their state of excitement, they beat upon the floor, and rub out the figure of the snake with palm flowers. This done, they proceed to the snake-grove, and prostrate themselves before the stone images of snakes, and recover consciousness. They take milk, water from a tender cocoanut, and plantains. The Pulluvan stops singing, and the ceremony is over. "Sometimes," Mr. Gopal Panikkar writes, "the gods appear in the bodies of all these females, and sometimes only in those of a select few, or none at all. The refusal of the gods to enter into such persons is symbolical of some want of cleanliness in them: which contingency is looked upon as a source of anxiety to the individual.
