Is it possible to exchange bodies with somebody else?
If yes, how to check if my beloved one is really who she is, same exact person, soul, heart, or whatever you call it, as she was just newborn?
Nope, not going to happen. We are tied to our physical bodies and there is no way that one can trade one body for another.
But of course your beloved is not the same person she was when she was born. Our life experiences are changing who we are all the time. But if you mean is the person you love still in the body in which she was born...then absolutely.
Thank you for your answers.
ZhenraKhal, I have neutral intentions, I am not specifically good neither bad. I just want to make sure that someone wouldn't try to pretend being someone else.
I have an interesting piece of information to share on this, somewhat related. Has to do with the exchange of souls. I have to get the full information first before I share it here. It is only theory but it makes a lot of sense and I believe it and even believe it happened to me.
