What I feel is summed up in both the Rig Veda and Guru Granth Sahib.
Basically, I don't believe that religion is a case of true or false, but I believe every religion is 'right', and all religions offer the right path to God - it all depends on what you are attracted to. Religion is not a one-size-fits-all. Some people are more interested in ascesticism, others are more interested in being homemakers, others are more interested in actions to helping humanity, others prefer a life worship.
All religions are human attempts at connecting to, and explaining, the Ultimate Source, whatever one calls it (I'm not after a debate about Buddhism and Jainism here) - and living morally. Since all theistic religions believe that God is indescribable, how can God be described, His existence penned, His Will explained? How can God be confined to just -one- religion? It makes no sense to me to believe that God, the Creator of the world, would bring his (successful) messengers into only one area.
Isn't it interesting how religions that are near to one another tend to have similar things in common? For example, Judaism, Christianity and Islam are all monotheistic religions and exclusive in their view of God, and (mainstream anyway) don't believe in reincarnation. In the East, Hinduism, Sikhism, Buddhism and Jainism all have dharma and reincarnation, and an inclusive view of religions. Religions in Europe were polytheistic prior to Christianization, the Romans and Greeks had very personal human gods. Why would this be? Because these religions are close to one another, and things are borrowed from each other.
In my view, it's a case of the blind men and the elephant. Each one touches only one part, and they compare notes to what they felt, and their views are different from one anothers, because none of them have the whole explanation of the elephant. It's the same with my view of God. Many colours, but the same spectrum. All religions have aspects of Truth, and all religions have aspects of falsehood and man-made traditions in them, they have all made one aspect less important and made another more important.
No religion is ultimately 'pure' nor 'superior' to another one, because all religions were revealed by mankind, and mankind has been responsible for spreading and raising them, as well as coming up with new philosophies such as "is blood transfusion allowed?", for example.
Just my $0.02 on this one.
(I know it's untidy (sorry!) but I've just wrote it all in one go.
You'd hate to be in this head, eh? It's all cluttered!)
