The world should know that Hinduism is not a Religion - but a name given by the Westerners because of their lack of understanding of the continent's religious approach. It is a way of life - where every individual can chose to be anything.
The name is Sanatan Dharma, or the Eternal Right, whose basis is on one Mahavakya, Great Statement, which says, "ekam satya vipraa bahudaa vadanti", meaning Truth is one but many speak differently.
The land of India, in Ancient Times, was following many paths to worships, and within Indian School of Philosophy had many paths, and was based on Religious Amalgamation and Syncretism.
This approach led to so called Hinduism becoming more like an University where one can wander and find the Truth his or her way without changing any religion. So with this approach, Jains, Buddhists, Sikhs, Zoroastrians, Jews, Christians, Muslims and Hindus lived together - but the friction with Muslims stands out. Compare to this, newer religions stand up as a College offering just one subject for PhD and Post Doc.
It was for this reason, India absorbed all Alien Cultural Invasions and assimilated them to be part of India and Hinduism.
The religious divides of Vaishanavites, Shaivism, and Kali Worshippers, and various schools of Indian Philosohies like Yoga, Vedenta, Sankhya, Naya, Vaisheshika, Purva Mimansa, etc. learnt to live together in peace and harmony - despite the class system.
If India was not one country, one would have found it hard to believe that the different East, West, North and South regions of the land belonged to one way of life, despite so many Gods and Goddesses of these regions. We were united by the thread weaving through so many pearls of wisdoms that the West started calling us Hindus.
But the same thread also was there amongst the states of Persia, Babylonia, Egypt, Greece and Italy. This the west calls it Proto Indo European Religion. Hindu influence was as far flung as Australia, Far East Countries,
Europe, and Middle East and West that it is hard to believe. We have
found Indian Gods and Goddesses statues in Australia, Indonesia, north
east of Moscow. If one studies the architecture of Pyramids of Mayans
and South Americas, and that of the Far East, one would see the
similarities.
The Religious wars were always between the Suras and Asuras - etymologically it breaks down to Suryas and Asuryas, or Syrians and Assyrians. The land of Arabia (non Sun Worshippers) were the Asuryas in the Indo European Religion. This war we see now is transformed into Islam vs Rest of World or Sunnis vs Shias.
There has been philosophical divides before but nothing like the mentioned before. Like Vesta vs Avesta, Ramaniya (Romania) vs Aramaniya (Armenia), Brahaman vs Abrahaman, etc.
