Russians have their Vedas,Perun Santees.

They are nine in number.

They seem to have been written in Gold( while Indian Vedas were transferred orally).

Russians beileve that a portion of it was given to Dravidas,people of South India,whise method of worship was different.

These Perun Santees date back to 600,000 years.

The portion given to India dates back to 40,000 years.

The similarities.

Perun Santees believe in one Reality.

There are expressed Gods out of this Reality.

The sign of Reality is Swasthika.

Their God of Thunder and Lightening ,Perun resembles Indra with his weapons.

‘In the classification scheme of Georges Dumézil, Perun was the god of the second function (physical and military power), a god of war, and as such, he was armed with several fantastic weapons. Perun’s lightning bolts were believed to be stones and stone arrows. According to folk beliefs, fulgurites, belemnites, and sometimes even the remains of prehistoric stone tools found in the ground are remains of these weapons. Various Slavic countries also call these deposits “Perun’s stones”, “thunderbolt stones”, “thunderbolt wedges” and “Perun’s arrow”; other unrelated names for these include “devil’s finger”, “God’s finger”, and “Mother of God finger”, and in Lithuania, “Perkun’s finger”  These thunderbolt stones were sometimes said to be transferred back to the sky by the wind after being under earth for a period of seven years. The weapons of Perun protected against bad luck, evil ,magic,disease,and – naturally enough – lightning itself.

Perun also had another type of weapon in his arsenal, as destructive as his firestone arrows, but even more unusual: mythical golden apples. While this may not seem to be much of a weapon, in many'( wiki Perun)

Perun Temple seems to have an Altar resembling Navagraha.

‘Remains of an ancient shrine to Perun discovered in Peryn consisted of a wide circular platform centred around a statue, encircled by a trench with eight apses, which contained sacrificial altars and possibly additional statues. The overall plan of the shrine shows clear symbolism of the number nine. This is sometimes interpreted that Perun, in fact, had nine sons (or eight sons, with himself, the father, being the ninth Perun). It should also be noted that in some Slavic folk songs, nine unnamed brothers are mentioned.( wiki Perun)

According to Perun Santees Fire God is to be worshiped as one finds in Vedas, Agni worship.

And there are ample references to Mitra Varuna,Mithraism.

There is a sect,Ynglism,which is based on Perun Santees and Book of Veles.

‘Ynglists teach that “Yngly” (Инглия) is the primordial fiery force from which the universe is arisen. They consider the Ynglings as the noble patriarchs of the Slavs and all other Indo-European (Aryan) peoples and civilisations, the first ones to get awareness of the Yngly. They also worship Rod similarly to other Rodnovers, but consider it the archetypal god of embodied men and the god of the begotten (manifested) world.

Their sacred texts are the Slavic-Aryan Vedas (Славяно-Арийская-Веды) and the Book of Veles. Although centered in the Omsk region, in recent years the church has extended its influence throughout Russia with local communities and a massive selling of books and other media.

Book of Veles is found to be a forgery.

Perun Santees seems to be authentic.

Slav Vedas. , http://vesna.atlantidaforum.com/?p=844

There is a view that there is a Fifth Veda, Pranava,Veda and Lord Subrahmanya taught this to Shiva at Swamimalai and hence called Swaminathan,the Perceptor to God.
