Power of words

I speak because I have you
I express through your power
I feel when you fall on my ear
whatever happens
I can't do without you
You fly me high
up in the sky
and take me low
below the valleys

You take me below the seas
make me dive into realities
of truth and death
I have you in smile
I have you in tear
I have you if i fear
All the time,
in sleep,
when I am awake
I speak through you,
You are the power vested in me
You are the words of strength for me!
