The Emptiness of Emptiness

18.

Whatever is dependently co-arisen
That is explained to be emptiness.
That, being a dependent designation,
Is itself the middle way.

19.

Something that is not dependently arisen,
Such a thing does not exist.
Therefore a nonempty thing
Does not exist.

Nagarjuna's Mulamadhyamakakarika, XXIV
