RAVANA IS LEGENDRY KING IN SRI LANKA

Ravana is a character in Hindu and Srilankan history, a powerful legendary king who ruled in Ancient Lanka (Present day Sri Lanka) and is the primary antagonist in the Ramayan epic.He plays a major role in the Hindu history Ramayana, where he is mainly depicted negatively as a brute, and most infamously as having kidnapped Rama's wife Sita.This depiction is, however, open to other interpretations. Ravana is also mentioned as a great scholar, a capable ruler, a player of the veena and a devoted follower of Shiva, and he has his apologists and staunch devotees within the Hindu traditions. The contrived meaning of "10 headed" as it is propagated by nationalists is that he possessed a very thorough knowledge in the 4 vedas, and 6 upanishadas (although the Upanishads number in their hundreds), which made him as powerful as 10 scholars. However, there is mention in Atharva Veda of demonic brahmans called 'Dasagva' (Ten headed) and 'navagva' (nine headed). These early beings may be the actual forerunners of the later character in the Ramayana.Ravana is also said to have authored Ravana Sanhita, a powerful book on the Hindu astrology, also known as Kaali Kitab. Ravana possessed a thorough knowledge of Ayurveda and political science. He is said to have possessed the nectar of immortality, which was stored under His navel, thanks to a celestial boon by Brahma.
