Imagine for a moment...
that there was someone who truly understands you. 
Someone who knows most of the questions you might not have even asked out loud. An answer different from the ones made of empty words. The fluff you've been hearing since you were little. An answer that would lift the weight off your chest with the very first words, after all these years. 

Now, add to that vision...
what it would be like to suddenly know yourself. 
I don't mean to start understanding yourself. Life can't be understood that way. Its heartbeat is to be the place where yours can beat undisturbed... without you having to beat yourself up for it. Again, and for the first time.

Gradually, that vision would become clearer...
along with the fog of your imagination, a fog you've known since childhood. The wind would blow away the clouds, and then your masks too. You could step out of the cage that was once your only safety, but has now become your prison. 

When you ask... "Who am I under all this?"
I will answer that you are precisely all of it.
