This is clearly false. My faith, Hinduism, has very clear spiritual teachings that are very very different from that of the Baha'i. Reincarnation, moksha, brahman, vegetarianism, the nature of the soul, the path to God, samadhi, kundalini, the use of murthis on worship, the nature of sound, inner light, chakras, monism, and much much more isn't even found in Abrahamic religions. I don't know how you can make such preposterous claims with a straight face?
Again, Krishna is GOD, not some manifestation. Your incorrect information and presentation may not be countered by the Baha'i echo chamber, but it won't be supported by any non-Baha'i either.
