But pure souls are assisted by the Good Spirits, the Triumph of the Good Principle is determined upon in the decrees of the Supreme Being, and the period of that triumph will infallibly arrive. At the moment when the earth shall be most afflicted with the evils brought upon it by the Spirits of perdition, three Prophets will appear to bring assistance to mortals. Sosiosch, Chief of the Three, will regenerate the world, and restore to it its primitive Beauty, Strength, and Purity. He will judge the good and the wicked. After the universal resurrection of the Good, the pure Spirits will conduct them to an abode of eternal happiness. Ahriman, his evil Demons, and all the world, will be purified in a torrent of liquid burning metal. The Law of Ormuzd will rule everywhere; all men will be happy; all, enjoying an unalterable bliss, will unite with Sosiosch in singing the praises of the Supreme Being. These doctrines, with some modifications, were adopted by the Kabalists and afterward by the Gnostics. Apollonius of Tyana says: "We shall render the most appropriate worship to the Deity, when to that God whom we call the First, who is One, and separate from all, and after whom we recognize the others, we present no offerings whatever, kindle to Him no fire, dedicate to Him no sensible thing; for he needs nothing, even of all that natures more exalted than ours could give. The earth produces no plant, the air nourishes no animal, there is in short nothing, which would not be impure in his sight. In addressing ourselves to Him, we must use only the higher word, that, I mean, which is not expressed by the mouth,--the silent inner word of the spirit.... From the most Glorious of all Beings, we must seek for blessings, by that which is most glorious in ourselves; and that is the spirit, which needs no organ." Strabo says: "This one Supreme Essence is that which embraces us all, the water and the land, that which we call the Heavens, the World, the Nature of things. This Highest Being should be worshipped, without any visible image, in sacred groves. In such retreats the devout should lay themselves down to sleep, and expect signs from God in dreams."
