Copy A, Plate 92
Although being fully human means being unified, achieving unity is facilitated through becoming conscious to the four forces which are active in the mind and in the outer world in which we live. An individual may unconsciously express in his behavior any of the four forces. Gaining an understanding of the dynamics of the interchanges of the four can enable the individual to quell the dissensions within and the conflicts encountered outwardly.
The image from near the end of Jerusalem when unity is being restored, shows the heads of four men emerging from the ground as if released to assume their proper places in the in the psyche of Albion.
Milton, Plate 4, (E 97) "Beneath the Plow of Rintrah & the harrow of the Almighty In the hands of Palamabron. Where the Starry Mills of Satan Are built beneath the Earth & Waters of the Mundane Shell Here the Three Classes of Men take their Sexual texture Woven The Sexual is Threefold: the Human is Fourfold" Jerusalem, Plate 12, (E 155) "Go on, builders in hope: tho Jerusalem wanders far away, Without the gate of Los: among the dark Satanic wheels. Fourfold the Sons of Los in their divisions: and fourfold, The great City of Golgonooza: fourfold toward the north And toward the south fourfold, & fourfold toward the east & west Each within other toward the four points: that toward Eden, and that toward the World of Generation, And that toward Beulah, and that toward Ulro: Ulro is the space of the terrible starry wheels of Albions sons: But that toward Eden is walled up, till time of renovation: Yet it is perfect in its building, ornaments & perfection." Jerusalem, Plate 98, (E 258) "The Sons & Daughters of Albion on soft clouds Waking from Sleep Soon all around remote the Heavens burnt with flaming fires And Urizen & Luvah & Tharmas & Urthona arose into Albions Bosom: Then Albion stood before Jesus in the Clouds Of Heaven Fourfold among the Visions of God in Eternity" Letters, To Thomas Butts, (E 722) "Now I a fourfold vision see And a fourfold vision is given to me Tis fourfold in my supreme delight And three fold in soft Beulahs night And twofold Always. May God us keep From Single vision & Newtons sleep"
