I have sometimes been allowed to sense the aura of malevolent falsity flowing out of hell. It was like a constant effort to destroy everything good and true, united to an anger, a kind of rage at not being able to do so. Especially, it was an effort to destroy the divine nature of the Lord because this is the source of everything good and true.
I have sensed an aura of benevolent truth from heaven, though, that served to restrain the rage of the effort rising up from hell, which yielded an equilibrium. I perceived that the sole source of this aura was the Lord, even though it seemed to be coming from angels in heaven. The reason it comes solely from the Lord and not from angels is that every angel in heaven admits that nothing of what is good and true comes from herself or himself, but that it all comes from the Lord.
