Ravana – The Great King, Alchemist & Physician of SriLanka
Ravana was the king of Lanka. His prosperity could be judged by the fact that his Lanka – capital city – was built in gold. Everyone had enough of food and shelter in his period.
Ravana was the eldest of the sons of Brahmin called ‘Vishrava’ and a princess called ‘Kaikesi’. 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 Shoorpanakha).
It is said there were 11 Ravans found in Sinhalese history such as Nala Ravana, Manu ravana, Punu ravana and Dasis Ravana. The most famous Ravana is the king who fought with Indian hindu prince Rama is Dasis Ravana.His queen was Mandodari, children were known as Upendraminika / Indrajith [Son] & Sohili [Daughter] .
King Dasis Ravana was a great Scholar in Ayurvedic medicine. He was the person who invented Arka Shastra. The book Arka Prakshaya reveals this truth to the present world. As he was willing to research in Ayurvedic medicine he wrote several books revealing the cures for many diseases.
Some of his books are; Oddisa Tantra, Kumara Tantra etc.
In one book he wrote “Eating beef cause to infect ninety eight new diseases to human beings”. The book “Kumara Tantraya” reveals the treatments for infant diseases was written accepting the request of his pregnant queen Mandodari.
He was the first king flew over the world with his aeroplane, known Dandumonaraya or Vimanaya, Kashtawahana. Some evidence of Dandumonaraya the aeroplane is found in Rock inscriptions, Jataka Stories and Ola manuscripts. It is believed he used Mercury as the fuel for that Dandumonaraya- the aeroplane. He was a “Siddha” person- who owed & had the special knowledge to use Mercury [Parada].
King Ravana was continuing a vegan oriented life style and was a real nature lover. According to Lankavatara sutta he was Buddhist and worshipped Kashyapa Buddha. Once he invited Kashyapa Buddha to visit Lanka and deliver his sermon to Sri Lankan citizens who practiced yoga and follow Buddhism.
Today the time has changed and most of us are not aware of the true history of king Ravana, not as just as a great king, but also as a great healer. Unfortunately, most of the people believe in the myths about Ramayana neglecting his great knowledge and skills. King Ravana was one of the best emperors in Sri Lankan History of Kingdoms.
