Sūtra translation
The non-existence (of external things, i.e., of the world) cannot he maintained, on account of our being conscious of them.
Further it cannot be said that the world itself is non- entity, or non-entity itself the world, for it is actually perceived (as entity), being the object of accurate know- ledge.
