LANKA

LANKA A strong fort like Lanka and the moat of sea around it-— such an abode of Ravana is no more traceable. (Asa Kabir, p. 481) The Fort of Lanka was made of gold; What did foolish Ravana take away with him ? (Bhairo Kabir, p. 1158) The island of Lanka as described in Ramayana was very vast and a plade of great magnificence. It had seven wide moats and seven walls of stone and metal. It was made of gold by Vishwakarma. According to Bhagavata Purana, this island was originally the summit of Mount Meru, which was broken off by the wind-god and thrown into the sea. See : Ravana
