Hinduism is so vast and so deep that even the most efficient learned persons of the West couldn’t analyse it as a single monistic culture.
Due to its profound vastness, to understand it clearly, the Western scholars divided Hinduism in four parts:
Actually these all four isms are not separate from each other originally.
If one peruses all these four isms s/he can easily find that all of these four isms have a common origin.
And that common origin is the original vast Hinduism according to Ved.
Believe it or not, but the facts speak for themselves and none can deny them without detrimenting him/her-self.
