Four Zoas, Night IX, Page 124, (E 394) "Then Urizen commanded & they brought the Seed of Men The trembling souls of All the Dead stood before Urizen Weak wailing in the troubled air East west & north & south Page 125 He turnd the horses loose & laid his Plow in the northern corner Of the wide Universal field. then Stepd forth into the immense Then he began to sow the seed he girded round his loins With a bright girdle & his skirt filld with immortal souls Howling & Wailing fly the souls from Urizens strong hand For from the hand of Urizen the myriads fall like stars Into their own appointed places driven back by the winds The naked warriors rush together down to the sea shores They are become like wintry flocks like forests stripd of leaves The Kings & Princes of the Earth cry with a feeble cry Driven on the unproducing sands & on the hardend rocks And all the while the flames of Orc follow the ventrous feet Of Urizen & all the while the Trump of Tharmas sounds Weeping & wailing fly the souls from Urizens strong hand The daughters of Urizen stand with Cups & measures of foaming wine Immense upon the heavens with bread & delicate repasts Then follows the golden harrow in the midst of Mental fires To ravishing melody of flutes & harps & softest voice The seed is harrowd in while flames heat the black mould & cause The human harvest to begin Towards the south first sprang The myriads & in silent fear they look out from their graves Then Urizen sits down to rest & all his wearied Sons Take their repose on beds they drink they sing they view the flames Of Orc in joy they view the human harvest springing up A time they give to sweet repose till all the harvest is ripe And Lo like the harvest Moon Ahania cast off her death clothes She folded them up in care in silence & her brightning limbs Bathd in the clear spring of the rock then from her darksom cave Issud in majesty divine Urizen rose up from his couch On wings of tenfold joy clapping his hands his feet his radiant wings In the immense as when the Sun dances upon the mountains A shout of jubilee in lovely notes responding from daughter to daughter From son to Son as if the Stars beaming innumerable Thro night should sing soft warbling filling Earth & heaven And bright Ahania took her seat by Urizen in songs & joy The Eternal Man also sat down upon the Couches of Beulah Sorrowful that he could not put off his new risen body In mental flames the flames refusd they drove him back to Beulah His body was redeemd to be permanent thro Mercy Divine"

Blake's poetry asks us to allow the symbol of the seed to be planted in us. And if it is, it will become active in our hearts, and minds and souls and bodies. The shifting of the imagery from 'souls of All the Dead,' to 'turnd the horses loose,' to 'sow the seed,' to 'fall like stars,' signals the transcendence of earthly events. The simultaneous harrowing of the seed and beginning of the harvest indicate the Eternal nature of the events being described.
The picture Blake uses with the text expands the imagery to include the seed as materialized humans carrying scraps of paper on which are written the words of life.
 And these are they which are sown on good ground; such as hear the word, and receive it, and bring forth fruit, some thirtyfold, some sixty, and some an hundred.
 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
 And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
Second Corinthians (JB Phillips Translation)
5:1-4 - We know, for instance, that if our earthly dwelling were taken down, like a tent, we have a permanent house in Heaven, made, not by man, but by God. In this present frame we sigh with deep longing for the heavenly house, for we do not want to face utter nakedness when death destroys our present dwelling - these bodies of ours. So long as we are clothed in this temporary dwelling we have a painful longing, not because we want just to get rid of these "clothes" but because we want to know the full cover of the permanent house that will be ours. We want our transitory life to be absorbed into the life that is eternal.
Marriage of Heaven & Hell, Plate 6,(E 35) "A Memorable Fancy. As I was walking among the fires of hell, delighted with the enjoyments of Genius; which to Angels look like torment and insanity. I collected some of their Proverbs: thinking that as the sayings used in a nation, mark its character, so the Proverbs of Hell, shew the nature of Infernal wisdom better than any description of buildings or garments. When I came home; on the abyss of the five senses, where a flat sided steep frowns over the present world. I saw a mighty Devil folded in black clouds, hovering on the sides of the rock, with corroding fires he wrote the following sentence now percieved by the minds of men, & read by them on earth. How do you know but ev'ry Bird that cuts the airy way, Is an immense world of delight, clos'd by your senses five? Proverbs of Hell. In seed time learn, in harvest teach, in winter enjoy."
