I.e., full insight into one's own self.
When a denier dies, they will realize that resurrection, judgment, Paradise, and Hell are all true.
What is stupor or unconsciousness to this probationary life will be the opening of the eyes to the next world: for Death is the Gateway between the two. Once through that Gateway man will realise how the things which he neglected or looked upon as remote are the intimate Realities, and the things which seemed to loom large in his eyes in this world were shadows that have fled. The things he wanted to avoid are the things that have really come to pass. Both Good and Evil will realise the Truth now in its intensity.
