I hate to interrupt, but since hinduism and bahai (according to your links and general consensus of what hinduism is) are so different, why call bahai interpretation of eastern mysticism, symbolizing their gods, setting aside their images hinduism?
Why call it something that it is not?
I mean I can say I believe in an absolute reality (not represent) and say the images are god (not representation of) but that doesn't make me a Hindu... as a bahai, why call it that in 'any' sense of the word?
Every worldview has a narrative that helps us make sense of who we are and who our brothers and sisters are. The Baha’i Faith is no different. Our view is world embracing. We have something simple yet powerful to say about Hinduism. 1/ Hinduism is a religion 2/ Hinduism has Divine origins. We further identify two men who emerged from the Indian subcontinent as being among the best of Divine Educators who walked the earth, Krishna and Buddha. That is not to deny many other outstanding teachers and gurus. However a Baha’i worldview sees Guatama Buddha and Lord Krishna as distinguished beyond other teachers and we consider then Manifestations of God. That is simply what the Baha’i Faith teaches. You are free to accept or reject such a view.
