The third state is one of repentance, a state in which he speaks piously and devoutly from the internal man and brings forth goods, like charitable acts which are nevertheless inanimate since he imagines that they originate in himself.

Arcana Coelestia #1524
1524. A blazing flame streamed down unexpectedly in front of me, blinding with its power not only the sight of my eyes but also my interior sight. Shortly afterwards a kind of obscurity appeared like a dark cloud containing so to speak something earthy. While I wondered at this I was led to realize that the light among angels in heaven is, in contrast to the light in the world of spirits, so much greater. Although spirits do live in light it is nevertheless as different as that. And as is the case with the light, so too are the intelligence and wisdom of angels superior to the intelligence and wisdom of spirits; and not only their intelligence and wisdom, but also everything connected with these, such as speech, thought, joy, and forms of happiness, for these correspond to the light. From this it has also become clear to me how great angelic perfection is, and what its nature is in contrast to that of men whose obscurity is even greater than that of spirits.
