How should I take the concept of 'non-entity'?

In this following context, how should I assume the concept of 'a perfect non-entity' Is it 'non-consciousness' or 'non-existence' or 'non- perception' or 'non- ego'? I think it refers to 'non-perception' according to this passage. But I'm not sure what should be taken here. let me know your idea.
