Who am I?

Who am I?
The call re-echoed through myself,
Still, calm and deep,
And present everywhere.
It roused me from my sleep.
I listened to the cry,
And wondered – Who am I?
And sought the answer through the mists of memory.

And as the time passed by
I heard myself reply,
I answered, I am nothing.

Nothing? – or everything?
I knew them as the same.
And I was filled with peace and calm content.
