Then Raphael, one of the Holy Angels who was with me, answered me, and said to me: "These beautiful places are there so that the spirits, the souls of the dead, might be gathered into them. For them they were created; so that here they might gather the souls of the sons of men. And these places they made to keep them up to the Day of Judgment, and until their appointed time, and that appointed time will be long, until the great judgment comes upon them. And I saw the spirits of the sons of men who were dead and their voices reached Heaven and complained....Then I asked about him, and about judgment on all, and I said: "Why is one separated from another?" And he answered me, and said to me: "These three places where made, in order that they might separate the spirits of the dead. And thus the souls of the righteous have been separated; this is the spring of water, and on it the light. Likewise, a place has been created for sinners, when they die, and are buried in the earth, and judgment has not come upon them during their life. And here their souls will be separated for this great torment, until the Great Day of Judgment and Punishment and Torment for those who curse, forever, and of vengeance on their souls. And there he will bind them forever. Verily, He is, from the beginning of the world. And thus a place has been separated for the souls of those who complain, and give information about their destruction, about when they were killed, in the days of the sinners. Thus a place has been created, for the souls of men who are not righteous, but sinners, accomplished in wrongdoing, and with the wrongdoers will be their lot. But their souls will not be killed on the day of judgment, nor will they rise from here."1Enoch 22.3 (But will merge with the basin of animal soul; Gaia.)
These underground places show great similarity with Hades, mentioned in the Bible and the Hindu Devachan.
