US-P08.004ab ।US-P08.004cd ॥
In plain words
I am my own, and only that — nothing else counts as mine. And I belong to no one: nothing ever touches me. Non-attachment is not something I practice, it is what I am. So nothing you do accomplishes anything for me, and nothing for you either — because there is no second thing here.
Close to the Sanskrit
I alone am mine; nothing other than that is admitted as mine. Likewise I am no one's — I am unattached. I am of the nature of non-attachment; therefore for me there is nothing to be accomplished by anything you do, and none for you either, because of non-duality.
