Intro:
======
Gm  Eb
Cm  Eb D


Part I:
=======
Gm    Dm    Bb    Asus4 A
Gm    Dm    Bb    Dm


Verse 1:
========
Gm 
  Conceal your deepest worries, confine your thoughts
            Eb                       D
Inside the walls you built of damaged pride
Gm
  The light in your eyes failing like you're adrift
              Eb                                D
Like night pretending to be day. These storms subside.


Chorus:
=======
Bb                              F                         Bb
  Though the past the unwanted memories are holding onto you.
                     F                            Bb
All the power in the universe conspires to carry you.
                              F                      
Truth you find through your adversities will defend you
Bb                             F                           Gm
  As your powers and all your energies conspire to carry you.


(Part I)


Verse 2:
========
Gm
 The adversary of your soul, the blackest thoughts
             Eb                        D
That try to poison you. These storms subside.
Gm
 Lay down your greatest burden. Relinquish that 
              Eb                         D
which has control of you and let yourself through


(Chorus)


(Part I)   3x


Part II:
========
Dm                             Bb
  Though it seems the past and future look the same
Dm                           Bb 
  Suffice to say that you're still here


(Chorus)


Outro:
======
Bb F Bb F ....
