In plain words
Mental projection too is ultimately non-dual, arising from association with an unreal object, just like the circular trail of a whirling firebrand. Because there is no intrinsic division into different powers or different selves, scripture establishes their absolute non-duality.
Close to the Sanskrit
Mental construction also thus should be non-dual from connection with the non-entity, like a firebrand circle. And there is no difference of powers or of selves; hence non-duality is ascertained from scripture.
