Yep. Jesus described it to John when he entered it to save the Jews who had died before truth and light came to man (as Christ):
"And I went into the realm of darkness and I endured till I entered the middle of the prison. And the foundations of chaos shook. And I hid myself from them because of their wickedness, and they did not recognize me.
"Again I returned for the second time, and I went about. I came forth from those who belong to the light, which is I, the remembrance of the Pronoia. I entered into the midst of darkness and the inside of Hades, since I was seeking (to accomplish) my task. And the foundations of chaos shook, that they might fall down upon those who are in chaos and might destroy them. And again I ran up to my root of light, lest they be destroyed before the time.
"Still for a third time I went - I am the light which exists in the light, I am the remembrance of the Pronoia - that I might enter into the midst of darkness and the inside of Hades. And I filled my face with the light of the completion of their aeon. And I entered into the midst of their prison, which is the prison of the body. And I said, 'He who hears, let him get up from the deep sleep.' And he wept and shed tears. Bitter tears he wiped from himself and he said, 'Who is it that calls my name, and from where has this hope come to me, while I am in the chains of the prison?' And I said, 'I am the Pronoia of the pure light; I am the thinking of the virginal Spirit, who raised you up to the honored place. Arise and remember that it is you who hearkened, and follow your root, which is I, the merciful one, and guard yourself against the angels of poverty and the demons of chaos and all those who ensnare you, and beware of the deep sleep and the enclosure of the inside of Hades.- Secret John
