You replace one belief with another. You can't be without a belief. What you call 'you' is only a belief.If you say :" I don't know who I am ", that's still a believe . If the belief goes, you go with it. That is the reason why, when you are not satisfied with one belief-structure, you replace it with another.
Oh boy..., don't believe in anything .....
