I'm bird

I'm   bird, from the kingdom of heave, 
Not made of dust.
For a short while,my body is a cage,
From which my soul shall bust

 **********************

Everyone is overridden by thoughts;
that's why they have so much heartache and sorrow.
At times I give myself up to thought purposefully;
but when I choose,
I spring up from those under its sway.
I am like a high-flying bird,
and thought is a gnat:
how should a gnat overpower me?
