A large percentage of what is found in Hinduism is also in our religion just using different names and terminologies. Hindus also try and live the truth as a Hindu serves humanity.
Hinduism is a true religion It teaches goodness and to serve all humanity. That is true
From a Hindu's perspective, that simply isn't true. What the Baha'i' do have is their own interpretation of Hinduism, not the Hindu interpretation of Hinduism. I can go walk the dog and say that I'm practising a version of Baha'i' because that's what Baha'i' do, but not too many people would believe me.
I would say yes, a tiny percentage of it is found in Baha'i', namely the core concept of ahimsa. But other core concepts like reincarnation, karma, temple worship, lineages, sampradaya, dealing with the physical body after death, God's nature, etc., are all different, sometimes slightly, but often radically.
