Valdai Glaciation
«Vritra erupted in terrible screams. The sides of the world, the firmament, the heavens, the earth and mountains trembled from his roar» and when «the inhuman cry of that great asura sounded: he opened his throat, (he shouted), gripped by a heavy fever… into his open mouth perun pierced the Chakra; the brilliance of that perun was very bright, it’s dying like a flame. Instantly, the huge body of Vritra’s smoke fell. «So, Indra’s celestial mace «forcefully chopped off the head of Vritra, who oppressed both worlds», as a result of which Vritra sank to the «bottom of space», and «the earth increased tenfold» and «the peoples could spread on it».
Thus, the great battle of Indra and Vritra, which was simultaneously taking place both in heaven and on earth, ended with the fact that «this mountain, the great, wide, with a club of thunder (Indra) … broke into pieces» and «released the bound water for running», he» drilled water (channels) … cut through the bowels of the mountains… how moo cows, rushing straight to the sea, run off the waters … (he) released seven streams for running… Through lifeless lying like crumbled reed (Vritra), flowing, billowing water Manu.»
Vritra himself, «faceless from the breach… crushed, lay scattered in different places.» It is characteristic that the nature of the relief has also changed.
«The land was stretched exactly, even the mountain, trying to escape, stopped. The mountain settled down, not dodging.»
It is interesting that it was 12 thousand years ago (i.e., at the turn of 11—10 thousand BC) that the Earth’s geomagnetic field changed.
We can assume that the myth of the battle of Indra and Vritra describes the interaction of a glacier with a space body. Moving at an altitude of 500 yojanas (8000 km.), It for some reason sharply braked and approached the Earth. At this time, probably, the breakaway parts fell and as a result of the impact of a sharp tidal wave and the rise of the earth’s crust, an earthquake occurred, volcanic activity began. Deviating to the southwest, the space object pushed a small cosmic body from its orbit over the Central Russian Upland (or a piece broke off from it).
The following lines of the Mahabharata also testify to the rotation of such a body in Earth orbit: «By that unbreakable, irresistible perun, arising from the Brahmin bones, penetrated by Vishnu, Indra killed Vishvaruna and cut off his head.
