Copy A, Plate 33
In William Blake's Jerusalem, Minna Doskow, explains how the Gate of Los allows for the movement between the temporal world and the eternal. Notice that the Eternal Urthona is transformed into Los to become active in time:
"It is named the 'Gate of Los', for Los is the connection between time and eternity, the crucial door of change through which states may be exchanged and vision altered ... All natural creations have gates to eternity within them, and vice versa, for all natural creation is potentially eternal. Functioning very much like the vortex in Milton, the Gate of Los entered one way, from eternity, allows eternal Urthona to become Los, the twenty-eight unfallen cities to be created by Hammer and Loom in order to save Albion, or Albion to go to death. Entered the other way, however, from time, it enables Albion or the reader to awaken and enter Eternal Life. ... Although 'Satan's watchfiends' are very thorough in their search for Los's gate, numbering every grain of sand on Earth every night, their scientific and analytic methods that Jerusalem warned Albion about earlier are exclusively material and therefor ineffective." (Page 84)
Milton, Plate 26 , (E 124) "So they are born on Earth, & every Class is determinate But not by Natural but by Spiritual power alone, Because The Natural power continually seeks & tends to Destruction Ending in Death: which would of itself be Eternal Death And all are Class'd by Spiritual, & not by Natural power. And every Natural Effect has a Spiritual Cause, and Not A Natural: for a Natural Cause only seems, it is a Delusion Of Ulro: & a ratio of the perishing Vegetable Memory."
Jerusalem, Plate 34 , (E 180) "So spoke London, immortal Guardian! I heard in Lambeths shades: In Felpham I heard and saw the Visions of Albion I write in South Molton Street, what I both see and hear In regions of Humanity, in Londons opening streets. I see thee awful Parent Land in light, behold I see! Verulam! Canterbury! venerable parent of men, Generous immortal Guardian golden clad! for Cities Are Men, fathers of multitudes, and Rivers & Mount[a]ins Are also Men; every thing is Human, mighty! sublime! In every bosom a Universe expands, as wings Let down at will around, and call'd the Universal Tent. York, crown'd with loving kindness. Edinburgh, cloth'd With fortitude as with a garment of immortal texture Woven in looms of Eden, in spiritual deaths of mighty men Who give themselves, in Golgotha, Victims to Justice; where There is in Albion a Gate of precious stones and gold Seen only by Emanations, by vegetations viewless, Bending across the road of Oxford Street; it from Hyde Park To Tyburns deathful shades, admits the wandering souls Of multitudes who die from Earth: this Gate cannot be found Plate 35  By Satans Watch-fiends tho' they search numbering every grain Of sand on Earth every night, they never find this Gate. It is the Gate of Los. Withoutside is the Mill, intricate, dreadful And fill'd with cruel tortures; but no mortal man can find the Mill Of Satan, in his mortal pilgrimage of seventy years For Human beauty knows it not: nor can Mercy find it! But In the Fourth region of Humanity, Urthona namd Mortality begins to roll the billows of Eternal Death Before the Gate of Los. Urthona here is named Los."
Jerusalem, Plate 77, (E 231) "Imagination the real & eternal World of which this Vegetable Universe is but a faint shadow & in which we shall live in our Eternal or Imaginative Bodies, when these Vegetable Mortal Bodies are no more. The Apostles knew of no other Gospel. What were all their spiritual gifts? What is the Divine Spirit? is the Holy Ghost any other than an Intellectual Fountain? What is the Harvest of the Gospel & its Labours? What is that Talent which it is a curse to hide? What are the Treasures of Heaven which we are to lay up for ourselves, are they any other than Mental Studies & Performances? What are all the Gifts. of the Gospel, are they not all Mental Gifts? Is God a Spirit who must be worshipped in Spirit & in Truth and are not the Gifts of the Spirit Every-thing to Man? O ye Religious discountenance every one among you who shall pretend to despise Art & Science! I call upon you in the Name of Jesus! What is the Life of Man but Art & Science? is it Meat & Drink? is not the Body more than Raiment? What is Mortality but the things relating to the Body, which Dies? What is Immortality but the things relating to the Spirit, which Lives Eternally! What is the joy of Heaven but Improvement in the things of the Spirit? What are the Pains of Hell but Ignorance, Bodily Lust, Idleness & devastation of the things of the Spirit[?]"
Four Zoas, Night IX, Page 122, (E 391) "The winter thou shalt plow & lay thy stores into thy barns Expecting to recieve Ahania in the spring with joy Immortal thou. Regenerate She & all the lovely Sex From her shall learn obedience & prepare for a wintry grave That spring may see them rise in tenfold joy & sweet delight Thus shall the male & female live the life of Eternity Because the Lamb of God Creates himself a bride & wife That we his Children evermore may live in Jerusalem Which now descendeth out of heaven a City yet a Woman Mother of myriads redeemd & born in her spiritual palaces By a New Spiritual birth Regenerated from Death"
Descriptive Catalogue, (E 544) "Acts themselves alone are history, and these are neither the exclusive property of Hume, Gibbon nor Voltaire, Echard, Rapin, Plutarch, nor Herodotus. Tell me the Acts, O historian, and leave me to reason upon them as I please; away with your reasoning and your rubbish. All that is not action is not worth reading. Tell me the What; I do not want you to tell me the Why, and the How; I can find that out myself, as well as you can, and I will not be fooled by you into opinions, that you please to impose, to disbelieve what you think improbable or impossible. His opinions, who does not see spiritual agency, is not worth any man's reading; he who rejects a fact because it is improbable, must reject all History and retain doubts only."
