Ravana is reported to have ruled during the period 2554-2517 BC. Ravana was supposed to have 10 heads, but Lankans feel that this represented the 10 kingdoms that he ruled. Ravana is very much a historical figure and historians generally credit him as the ruler of Lanka with his headquarters at Polonnaruwa which is located in North Central Sri Lanka.
Hindu texts of that period also credit Ravana as a man who ruled the 3 worlds and was a follower of Shiva, the creator and destroyer. He is reported to have been administered the juice of immortality by Shiva. He had also mastered the Vedas and all the religious books of the Hindus. Hindu texts also agree that Ravana was a virile king, who was fond of women, his favorite wife being Mandodri.
Indian texts in particular the Ramayana mention that Ravana abducted the lovely Sita from the Jungles of central India and took her to Lanka.He was the son of a Brahmin called ‘Vishrava’ and a princess called ‘Kaikesi’. When Kaikesi came of age to be married, her father ‘Sumali’ the king of the Daityas, wanted her to marry the most powerful and noble man in the world. He refused a lot of offers made by a number of princes and went to Vishrava instead. He agreed to marry Kaikesi. Yet, he told that Kaikesi approached her in the wrong time, and the children that were to be born to them will be bent towards evil.
Ravana was the eldest of the sons that they had. He was named “Dasagriva” or “Dashanana” since it is believed that he had ten heads. But this may be because he had the power and strength of ten men. Some say the ten heads were due to the reflections of a crystal necklace gifted to him by his father at the time of his birth or he had the mental strength of 10 people. Ravana had two brothers, Vibhishana and Kumbhakarna and one sister, Meenakshi (Later named Supernlakha,)
He did lavish gifts on her but the core issue is untouched. As Rama was the 8th avatar of Vishnu perhaps in deference to Rama this issue is left untouched. But now people in the 21st century can draw their own conjectures. Would Ravana a virile king spared Sita?
