। ॥ ५६७ ॥
In plain words
Scripture says it outright, on its own authority: the self is of both natures. So the self is taken to be bodied out of consciousness and inert matter together — like a firefly.
Close to the Sanskrit
She herself declares the twofold nature of the self. Hence the self, having a body of consciousness and inertness, is held to be like a firefly.
