No they don't usually. But in Buddhism and Hinduism (at least concerning Krishna in Hinduism) reincarnation, for instance, is in the scriptures, and if that is proven to be true, that is inconsistent with what Baha'u'llah and Abdu'l-Baha says, and since Krishna and and Buddha are considered Manifestations in our faith, then either they are not Manifestations, and thus our faith is wrong about that, or our faith is wrong about reincarnation.
That's very much how I'm looking at it. The resurrection in Christianity and reincarnation in Hinduism are the two I talk about the most with Baha'is. I'll start with the resurrection first.
To me, it sure sounds like the gospels say Jesus came back to life. They touched him, talked to him and he said he is not a ghost but has flesh and bone. Great. He's real and alive.
But then people don't recognize him. He walks through doors and walls, appearing and disappearing, then ascends into the clouds?
The Born-Again Christians... It all happened. Jesus is alive and at the right hand of God and is coming back.... soon.
Baha'is... Can't be literal. People can't come back to life after being dead that long. Besides that, a physical body can't go through walls and float off into space. Using science and reason, we know that's not possible. Therefore, there must be another explanation. These verses must be symbolic.
For me, I make it even simpler. The legends and traditions of his resurrection were passed on. The gospel writers put them into writing. I don't see them writing about it as if it were some "symbolic" thing. They wrote their stories in a way that proves... Jesus was alive.
Of course, if it's not true, that's a terrible hoax to pull on the people. But did Jesus walk on water? Did he cast out demons? Did he raise Lazarus from the dead? Did people come out of their graves in Jerusalem? Then if we go back to the Hebrew Bible... Did Elijah call down fire from the heavens? Did he fly off in a fiery chariot? Did Mose's staff turn into a snake? Did the waters part?
I don't know? These things sure sound like made-up legends and myths to me. Why not the resurrection story too?
So, I agree with the Baha'is that it didn't literally happen. But I disagree with them that the writer's meant for it to be taken symbolically.
Same kind of thing with Reincarnation. I don't know all the details about Hindu beliefs, but I'd imagine that all their beliefs lead up to reincarnation being what happens. We can't just pull reincarnation out without making changes in the other things they believe in.
Again, I don't see how a "symbolic" explanation fits. Hindu Scriptures are talking about a soul coming back into a different body. While in that body, it learns, grows, makes mistakes and then that body dies. Wherever they say that soul goes, it waits and gets put into another body and learns some more. Bad and good karma are involved. And eventually the soul has grown spiritually to where it doesn't accumulate any more bad karma and has dealt with its past bad karma. Their beliefs describe that whole process.
But... what if reincarnation isn't true? What if that whole process was just something that Holy people of that culture came up with as an explanation of how things were?
Then it's not something that some God/man, or incarnation, brought them. But that's what the Baha'is are up against. They look at it as if Krishna supposedly taught this... but really didn't. That Krishna taught something that was misinterpreted to be about reincarnation. For me, that's way too complicated and unlikely.
So, the resurrection literally true? Maybe... but for me, unlikely. Symbolically true? I don't think so. It just wasn't written in a symbol-style. They wrote it as if those things really happened. Made up hoax? Maybe. But how did they pull it off? So, after all that... I don't know.
Reincarnation? Hey, I don't know. But I like the idea. But if the Baha'is have people learning and growing spiritually in some other spiritual worlds of God, then to me, that's better than the Born-Again Christian belief of heaven for believers and hell for everybody else.
So, for Christians and Baha'is... I'm not saying that what you believe isn't true, I'm just saying I doubt that it's true.
