Uttara Kanda (Also other Kandas) of Ramayan mentions Ravana having 10 heads and 20 arms.
Now 10 heads would make a body asymmetrical as there is no middle point.
Is there any mention in scriptures which tells us to which head among the 10 was Ravana's body attached to? Also Ravana is called Dasagriva meaning having ten necks. If such is the condition how were his necks attached ?
Were they in linear design or in circular design? E.g., did his right side contain more heads or his left side (when he used to be in the form of 'Dashanan')?
Do any scripture mention about this ?
