I have written on Baikal being of Indian origin and Arkaim being the land of Sanatana Dhrma, not to speak of the fact that the Rig Veda was composed in the Arctic.
The Puranas describe, while talking about the Earth, say that there was Ilavarsha and they talk, along with the Ithihasas Ramayana and Mahabharata bout Amaravathi, the capital of Deva Loka of Indra.
The huge circle in the above diagram shows the extent of“Sudharshana Dweepa” where the rule of Sanatan Dharma was in place.
It had Bharath in the South (rectangle area in the bottom of this picture) with
Hemakuta or Himalayas in its northern limits,
an intermediary Ilavarsha to the north of Himalayas (noted in dark red square in the middle) and
a vast Airavatha varsha in extreme north of the Sudharshana dweepa..
Most of Russia come Airavatha Varsha and Airavatha is the name of Indra’s Elephant.
The Deva territory is close to the North pole where there was sunlight continuously for 6 months and darkness continuously for 6 months. The elephant, Airavatha in all probability was the Woolly mammoth ,which became extinct about 10,000 years ago. ..
Part of Uttarakuru Region.
Uttar kuru means the land of Kuru (a clan) settled in the North. They were the early settlers much before Mahabharatha times (which was about 5000 years ago.) The men and women of that territory were said to have led a free life and mingled with each other as they wished. The probable reason could have been procreation which was minimal owing to climatic conditions that existed there.
There is an opinion that the name Russia was derived from Rishi varsha. There is a mention of Rishi varsha in scriptures which goes well with this region. The presence of Devas in this part of the globe in a distant past had attracted sages to this place. We have a number of references in Puranas of sages going to the Deva territory. Perhaps their overwhelming presence gave the name Rishi varsha which later became Russia.
There is yet another root to the name Russia as being derived from the olden name of Volga river. Volga was called as ‘rasa’ or ‘rosa’. People think that it is derived from the Persian word ‘rana’ or ‘ra’. But this word ‘rasa’ is a straight Sanskrit word meaning essence, juice, nectar, elixir, soup, love, the finest part of anything and so on. This name perfectly fits with the river of fine water quality From the river’s name Rasa, the name Russia was derived.
