Truth is eternal. That truth is one. There might be many different pathways to truth. Some Hindus might take the pathway of devotion or of knowledge or of duty, but they're all seeking that one reality, that one truth that transcends even Hinduism itself. Their second core belief is that there is one God. They're not really polytheistic. We can kind of understand why some people might say that in a second, but they do believe that there is one world soul called Brahman and that out of that one world soul, there's manifestations through other gods and goddesses.
