In Hindu mythology Ravana, the king of Sri Lanka supposed to possess ten heads. Physically it was impossible to carry ten heads on a single neck and ten brains to be supplied with a single heart. Brains cannot live or work without sensory and motor nerves. Therefore, the concept of ten heads is illusion. Functionally Ravana was a sane person and skilled warrior and possessed no double personality or more. So why Ravana was attributed with ten heads? As discovered from Google search two faces possessed with double noses, eyes could be more and ear abnormalities are common, it is deduced that Ravana was having multiple ears, eye and noses planted on a single cranium as if conceptualized as fused ten heads (craniopagus).
