Sanathana Dharma - will this continue its record of longivity?

Re: Sanathana Dharma - will this continue its record of longivity?

I am not saying Hinduism has the correct answer to everything (or even most things). What I am saying is that if the Imam Mahdi (pbuh) were to appear and Hindus begin to follow him, they will accept whatever he preaches no matter if he contradicts some Hindu text - meaning Hindus are flexible enough to adjust to new teachings from new Spiritual Teachers.

However, if the Imam contradicts something in the Bible, many Christians will refuse to follow him. If he contradicts something in the Koran - many Muslims (most Muslims?) will not believe in him anymore.

As for whether he will teach anything new, I think we should leave it up to him. He is not bound by any book as to what he should do. I am sure he will do whatever is best for humanity.

However, it is my personal belief that he will come as a teacher with new teachings. Hindus believe (or at least I do) that Avatars such as him come periodically to the world with new teachings to expand upon existing one. It is like Quantum mechanics expanding upon Newtonian mechanics - it does not contradict old religion doctrines, just gives more detailed information.

For example, if the Imam Mahdi says reincarnation is a fact, how many Muslims or Christians will follow him? (I am not saying he will, maybe he will say reincarnation is totally false, who knows?).
