Some random thoughts on Aryan themes in Indian polity.
1)The people of southern TN are darkest while Cashmeres are fairest.The skin colour becomes darker towards south and east.
2)THe aryan-dravidan meme is strongest in TN.East Bengali peasants converted to Islam.The majority of Hindus in East Bengal were chandalas(rechristened namashudras)
3)Bihar was the leader of the heterodox challenge.Buddha who rejected Vedas attained enlightenment in Gaya.
4)The greatest Shiva temple(in terms of prestige) is Vishwanath temple,Kashi in Eastern UP.
5)Afghans ridicule pakjabis as originally worshippers of shivalingam who were brought to the "Light of Islam" by Mahmud of Ghazni.
6)The greatest no ofhymns in Rigveda is for Indra,Varuna,Agni but Hinduism is defined by worship of Shiva,Narayana and Mother goddess.Narayana is not a word/term found in the samhita portion of vedas according to scholars.
7)Mother Goddess(Kali/Shakthi)worship is almost absent in Rigveda.
The Aryas worshipped by yagnas.Temple worship is the main mode of worship for hindus including brahmanas today.
9)The right to study vedas is strictly limited.Brahmanas have gotras.
10)The Rigvedas geography is NW India+Kubha river in afghanisthan according to scholars.The Yajurvedas geography indicates a shift towards Eastern UP+Mithila and awareness of southern people like andhras.
11)All evidence suggest that Aryas had an extraordinary tradition called vedas and those people were shifting to east and they were assimilating ideas/beliefs(Shiva/Narayana/Atman/Karma).In time West Punjab was becoming unorthodox and the centre of gravity of Arya people became UP.Yet in the far east,East Bengal was anaarya.These were vraatyas-beyond the pale.Paundra Vasudeva was the imposter par excellence.
Hindus of North India see themselves as defenders of Vedic heritage though in reality it is the southern brahmanas who defended vedic orthodoxy most as North India capitulated before muslim aggression.The north indian polity and society was incapable of resisting mlecchas.It seems as if something greater than literal veda was at work.(Karma?)Pakjab became muslim and perhaps even East Punjab would have succumbed but for the message of Veda.Nanak who rebelled against vedic literalism saved the day for "Hindu"Punjab.
There is a verse in Upanishad which I am not able to locate.May be some one in BRF can help.
"The Veda is there not for Vedas sake but for the sake of Atma"
