IT is certainly a temple with a difference. In the heart of central Kerala, some 150 km from Thiruvananthapuram, Mannarssala is a sylvan nine-acre paradise of bamboo thickets, entwined creepers and banyan trees. Dangerous snakes, like cobras and kraits, slither in the shrubby vegetation. In the middle of this lush and riotous green landscape stands the fabled snake temple by the same name. Snake worship here, according to legend, has been going on for the past eight centuries.
