Just A Thought

Imagine there are no bars
Imagine the door is open
Imagine your wings
have not been clipped.

The voice in the clouds -
The song of the earth -
What do you hear?
Where do you go?

Imagine you know nothing
Imagine your past is past
Imagine the future matches
none of your predictions -

Look down now
Look up! Realise
there is nothing to
hold you here: now!

Your wings reach to cover
the entire realm of creation
Your door admits everything
You ask: What are  "bars"?
