ETERNAL DEED II

In the continuation of the passage from Plate 55 of Jerusalem in which 'an eternal deed was done' Blake states that the Seven Eyes of God were elected. He gives each a name used for God and mentioned in the Bible. Each name is used symbolically to recall a period of history characterised by behaviors and attitudes prevalent in the development of humanity at a particular time. Blake's insight is that cultures are progressing through phases of development which are built on previous experiences. The errors which are revealed through adherence to prevailing ideas, as well as the opportunities which become apparent through apprehending new truth, impel mankind to explore options which were formerly closed to him. 

Jerusalem, Plate 55, (E 204)
"But others said: Let us to him who only Is, & who
Walketh among us, give decision. bring forth all your fires!

So saying, an eternal deed was done: in fiery flames

The Universal Conc[l]ave raged,
...

Then far the greatest number were about to make a Separation

And they Elected Seven, calld the Seven Eyes of God; 
Lucifer, Molech, Elohim, Shaddai, Pahad, Jehovah, Jesus."

 
Blake saw the passage through these phases of development as synonymous with encountering the 'seven Spirits of God' or the Lamb 'having seven horns and seven eyes', which are two images used in the Book of Revelation. As the seven Spirits were sent forth into all the earth in the Book of Revelation, Blake's Seven Eyes were the provision that the Eternals made for the contingent that separated and 'who Walketh among us.'

[6] And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth. (Revelation 5)

Blake further saw that the psychological and spiritual development of the individual progressed through the stages represented by the Eyes of God. The formation of the psyche is not accomplished in a single step, but proceeds through multiple steps. Especially in Blake's set of Illustrations of the Book of Job he shows the psychological process through which an individual psyche is restructured to accommodate a real relationship with the Divine.

"The Family Divine drew up the Universal tent
Above High Snowdon & closd the Messengers in clouds around 
Till the time of the End. Then they Elected Seven. called the Seven
Eyes of God & the Seven lamps of the Almighty                    
The Seven are one within the other the Seventh is named Jesus"
