Nanach gives and build Personality and Character!

Nanach is truly amazing and wondrous! When one associates himself with Nanach he benefits in infinite ways! Nanach will give and build his personality and character!
This can be understood very simply, before one begins Nanach, he doesn't exactly know what he's doing in the world and what everything is about. Sure he'll say bold statements like, the main thing is to learn as much as possible, but the reality is he never put his ideals to the test and not only is he not really sure about what he means to say he doesn't know where it will take him and if it's for him at all. So this person will find himself with a false sense of security and haughtiness.
Whereas as soon as he begins to experience Nanach he will begin to touch base not only with G-d and Rabbi Nachman, but with himself.
This is on of the interpretations of what the Saba frequently said, "I am Na Nach Nachmu Nachmun MayUman!, because the I, can not simply refer to one's brain or heart, because a persons identity can not be summed up as just that. 'I' can not even, as Shlomo Carlbach points out, simply refer to ones mind and soul, because even that isn't a complete representation of a person, as we say in the early morning prayer אלהי נשמה שנתת בי וכו' - My G-d the soul that you have place in me, this prayer makes it clear the soul is just a placement in a persons identity. Rabbi Nachman revealed through the Saba that a person can find and build his identity at Na Nach Nachmu Nachmun MayUman!
Thus we see so many people who transformed so quickly after becoming Nanach. They immediately gained direction and purpose. They gained for themselves understanding of what they are really about, what the world is really about, and what to about all of it!
They built their personality and character simply by becoming Nanach!!!
