Oushi appears to be talking about "Sealing the view with the object of emptiness". This means that once a person has realized the truth of emptiness, rather than abiding within that emptiness without any conceptualization about it, they start labeling everything as "empty". This is empty, that is empty, I am empty, look at all the empty things!
Everything is empty, according to Buddhism. How could one thing be empty but not something else?
But that is a contradiction because emptiness implies the non-existence of things whatsoever, so its just a continuation of previous mental imputation onto non-existent objects.
It means they don't exist in the sense of being independent or permanent and unchanging.
This in turn leads to Nihilism because such a person has not realized Dharmakaya. Emptiness has become an object of mental fixation, rather than an experience of abiding in the true nature of reality itself without fixations.
Nihilism does not mean any particular sort of mental fixation, such as fixation on the Buddhist concept of emptiness.
In terms of meaning, Nihilists believe there is no meaning to anything because its all empty.
According to Buddhism everything is empty, so if what you're saying is true then all Buddhist who haven't realized and 'abide' in emptiness are nihilists.That isn't right, right?
