What is the syntax in "what I do is me - for that I came" ?

Is this a quote from Ray? Please clarify so we can help you.

It is the title of one of his writings

It sounds to me like he's saying he has no choice but to write--it's in his blood, and happily so. I've heard him say the characters just start talking to him some mornings, and he must get up and put it all down on paper, like they take hold of him and he must comply. I think he feels he was put on this Earth to write, and to write as much as possible. When I met him at a bookstore several years ago, he told me to tell my seventh graders that that is the age when he began writing, and that he had never once taken a day off from writing. When I asked if he hadn't laid off for a day or two, like on a vacation, he said that you don't need a vacation from something you love so much.

Moreover, it took on some of the forms of an addiction or dependency. He has said he experienced physical pain if he couldn't be writing at least four hours a day.

It's from one of Ray's poems. Forget exactly where that line is, but it is in one of his poems that goes something ike this::

God thumb-prints thee....
Be not another. Be not grandfather, or grandmother, aunt or uncle... etc.. God breathes ''you'' into being. Be not another...

It goes something like that....
