Frontispiece, Copy B
Los is forever entering the door of the dark underground carrying his illumination. He enters the interior of Albion and finds the expressions of his Divine Humanity distorted by a hidden influence. In this passage the light of his globe of fire reveals a hardening of the minute particulars into grains of sand. No action that Los can take can remove the damage he sees.
He sees that the problems he encounters are connected to the exercise of the moral law which hardens men against their brothers. The moral law is a system which sustains itself by allowing vengeance in return for offenses. Reaction to the system involves one in the system which is the source of the damage.
Los with his globe of fire must continue his journey through the dark places making known the disastrous consequence that man inflicts upon himself by turning against the Divine Vision.
Jerusalem, Plate 44 , (E 194) "So Los in lamentations followd Albion, Albion coverd, Plate 45  His western heaven with rocky clouds of death & despair. Fearing that Albion should turn his back against the Divine Vision Los took his globe of fire to search the interiors of Albions Bosom, in all the terrors of friendship, entering the caves Of despair & death, to search the tempters out, walking among Albions rocks & precipices! caves of solitude & dark despair, And saw every Minute Particular of Albion degraded & murderd But saw not by whom; they were hidden within in the minute particulars Of which they had possessd themselves; and there they take up The articulations of a mans soul, and laughing throw it down Into the frame, then knock it out upon the plank, & souls are bak'd In bricks to build the pyramids of Heber & Terah. But Los Searchd in vain: closd from the minutia he walkd, difficult. He came down from Highgate thro Hackney & Holloway towards London Till he came to old Stratford & thence to Stepney & the Isle Of Leuthas Dogs, thence thro the narrows of the Rivers side And saw every minute particular, the jewels of Albion, running down The kennels of the streets & lanes as if they were abhorrd. Every Universal Form, was become barren mountains of Moral Virtue: and every Minute Particular hardend into grains of sand: And all the tendernesses of the soul cast forth as filth & mire, Among the winding places of deep contemplation intricate To where the Tower of London frownd dreadful over Jerusalem: A building of Luvah builded in Jerusalems eastern gate to be His secluded Court: thence to Bethlehem where was builded Dens of despair in the house of bread: enquiring in vain Of stones and rocks he took his way, for human form was none: And thus he spoke, looking on Albions City with many tears What shall I do! what could I do, if I could find these Criminals I could not dare to take vengeance; for all things are so constructed And builded by the Divine hand, that the sinner shall always escape, And he who takes vengeance alone is the criminal of Providence; If I should dare to lay my finger on a grain of sand In way of vengeance; I punish the already punishd: O whom Should I pity if I pity not the sinner who is gone astray! O Albion, if thou takest vengeance; if thou revengest thy wrongs Thou art for ever lost! What can I do to hinder the Sons Of Albion from taking vengeance? or how shall I them perswade. So spoke Los, travelling thro darkness & horrid solitude:"
 For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and spirit, of joints and marrow, and discerning the thoughts and intentions of the heart. And before him no creature is hidden, but all are open and laid bare to the eyes of him with whom we have to do.
