Hi Renuka,
You may be interested in - Vatapi Ganapathi now installed inTamil Nadu – Tiruchengattangudi, was personally worshipped by King Ravana. KingRavana, the only mythical Brahmin King was a great Sanskrit Scholar & aworshipper of Shiva. Lanka stands for “SacredIsland” in Sanskrit.
So Sanskrit language, 4 Vedas, manusmriti, Upanishads,Shaivite philosophy, all our religions, all originate in this sacred Island from theRavana Kingdom & after the fall, the Brahmins move to the other kingdoms / TamilNadu & continued this work leading to the Advaita & Dwvaitaphilosophies of Adi Shankara & Ramanaujam.
By the way, did you know we already worship Ravana ?. It isRavana who is Brahma in our texts. In some statues, Ravana is seen as 3 headed.
Cheers,
