Nagarjuna also stated nirvana is peace. The Shentong point about sublime vision of the realized beings holds up. We are talking about the mind, not mental faculty, but the nature.
In terms of the path, there is no difference at all between the Yogacara presentation and the Madhyamaka presentation, so this is a kind of redundant thing to say.
The controversy is over whether there is a difference in view between Yogacara and Madhyamaka.
gzhan stong pas are Tibetan partisans of Yogacara who assert a)there is a diference between Cittamatra and Yogacara, and b1) Yogacara is either higher than Madhyamaka b2) or is a form of Madhyamaka with a difference in emphasis.
Basically, there are three alternatives:
Madhyamaka is higher than Yogacara
Madhyamaka and Yogacara have the same meaning with different emphasis
Madhyamaka is inferior to Yogacara.
Because Madhyamaka is primarily a tool to destroy the views of other schools. It doesn't establish it's own view. But Yogacara, as I see it, just goes one step farther and says, "by the way, the buddhas have
sublime vision." The sublimity is beyond non-existence while also being
unconditioned. This is sort of as far as one can go, because the moment one tries to pinpoint what is unconditioned, there's nothing to point to. No possessor or existing thing. This experience itself points out the magically luminous nature of mind. Statements like this about luminosity, bodhicitta and such are what mediate against the "nothingness bias" can creep in during dharma study.
