That is not the teaching of Nagarjuna. Nagarjuna's Mulamadhyamakakarikas have extensive proofs for how all conditioned phenomena are empty, and Nagarjuna also proves that unconditioned phenomena are empty. For example, he writes:Stefos wrote:So again to clariy, For me there IS a substratum: Emptiness, Clarity and Bliss
Is this what Sri Nagarjuna taught?
For Nagarjuna, the very idea of being conditioned or unconditioned form a pair, and so both depend on one another, and you can't have one without the other. You can't have unconditioned phenomena without conditioned phenomena anymore than you can have north without south, or hot without cold.As arising, abiding, and cessation are not established,
There is nothing that is conditioned.
Since the conditioned lacks any establishment,
How could the unconditioned be established? [VII.33]
I don't know much about Dzogchen, but I know that Longchenpa is considered to be one of the most important Dzogchen teachers in history, and according to him, the view of Dzogchen is equivalent to Prasangika Madhyamaka, so I don't see how Dzogchen could accept any sort of real phenomenon either, whether conditioned or unconditioned.

assist me in understanding the view of emptiness in terms of the Dharmakaya?
