I think these Wikipedia articles are necessary reading for any individual seeking to understand the Truth, but who isn't sure where to start:
article on Hinduism was very balanced and gave exactly the right amount of space to the blind, ritual based variety of Hinduism practiced by the majority of Hindus. In fact, what was most interesting was that the URL of the article was http://en.wikipedia.org/wiki/Sanatana_Dharma, Sanatana Dharma being the overarching philosophy of Hinduism from which the religious aspects are derived. There is also a clear explanation of the Hindu concept of God, which most occidentals (hell, most practicing Hindus, even) are unaware of.
The section on Conversion to Hinduism also makes for interesting reading. Something all the Christian priests running around India in their headlong rush to convert the masses of heathens probably need to look at first. Ditto for all the Hindutva brigade goons and their cobbled together rituals to convert back the converted.
Why don't they get it? You can't stop someone from being Hindu with some ridiculous ritual. You can't make someone a Hindu with an equally ridiculous ritual. Hinduism is the pursuit of the Truth. That's it. If that is what you're doing, then you're Hindu. If you aren't, then you're not.
