। ॥ ६७८ ॥
In plain words
In the one Reality, the supreme Self that has no second, difference is simply not there. And the difference produced by something of another order falls away with the negation of the whole spread-out world.
Close to the Sanskrit
Difference is not found in the Reality, the second-less supreme Self; by the negation of the manifold world, the difference made by what belongs to another class [is set aside].
