Yeah! If there's something like rebirthing that must be the change of our minds. When somebody adopts new paradigms about something that is essential to his/her life, then we can say he/she is not the same anymore, he is another one. To get a new way of living we have to "kill" our old behavior though. You can notice that the concept of "rebirth" implies the notion of "death". As someone said once "Destruction is creation".

When people set new goals or objectives for life they're "rebirthing", they enter into a new experience that will cause them to think, behave and feel differently than they used to. Perhaps you have known someone who have his/her "turning point" in life. That's the kind of rebirth I'm talking about.

Everyday we're changing, because of the learning process, but we don't realize about that, nor we realize about the things that influence us. However, that doesn't mean that frequently we are "dying" and "rebirthing".

I hope that answear your request dear.
