Section XXVI of the Astika Parva of Mahabharata mentions the incident of Garud and his mother Vinata carrying snakes and their mother Kadru to an island called Ramaniyaka.
The next section describes it thus:
"Sauti said, 'And then the Nagas drenched by that shower, became exceedingly glad. And borne by that bird of fair feathers, they soon arrived at the island. That island had been fixed by the Creator of the Universe as the abode of the makaras. There they saw the terrible Lavana Samudra (ocean of salt). On arriving there with Garuda, they saw there a beautiful forest washed by the waters of the sea and resounding with the music of winged choirs. And there were clusters of trees all around laden with various fruits and flowers. And there were also fair mansions all around; and many tanks full of lotuses. And it was also adorned with many lakes of pure water. And it was refreshed with pure incense-breathing breezes. And it was adorned with many a tree that grew only on the hills of Malaya, and seemed by their tallness to reach the very heavens.
Given that the salt-ocean is mentioned along with the Malaya hills that form the lower part of the western ghats, is there a way to identify this island?
