Nurmi illustrated that the arrival at 'spiritual sensation' was reached through the steps which Blake enumerated in the poem. Quoting from Nurmi on page 554: "In the first part of the poem, which records a visionary experience on the sand at Felpham, the sand appears merely as 'Jewels of Light.' Then as Blake's vision becomes more intense and passes firmly into its 'two-fold state, the grains of sand begin to display their human quality, and appear as individual men:"
I each particle gazed Astonishd Amazed For each was a Man Human formd. ... "We fail to recognize the human nature of creation because we look as if from a distance"
Each grain of Sand Every Stone on the Land Each rock & each hill Each fountain & rill Each herb & each tree Mountain hill Earth & Sea Cloud Meteor & Star Are Men Seen Afar"This two-fold perception is superior to the 'single-vision' of the materialistic philosopher because it begins to show the imaginative form of things. But it does not yield a comprehensive view of the world. To gain that we must pass through an affective state, the 'three-fold vision' in which objects undergo a transformation because the perceiver undergoes one: He begins to view all things in a state of delight somewhat akin to the sexual delight with which man looks on woman."
I stood in the Streams Of Heavens bright beams And Saw Felpham sweet Beneath my bright feet In soft Female charms"In this state he can begin to know directly by perception that on Earth there are only shadows, that the Real is elsewhere:"
My Shadow I knew And my wifes shadow too And My Sister & Friend. We like Infants descend In our Shadows on Earth Like a weak mortal birth"Having passed through this state, the perceiver is now ready to move to the highest state, oe 'four-fold' vision which enable him to see all of existence synoptically as one, as 'One Man':"
My Eyes more & more Like a Sea without shore Continue Expanding The Heavens commanding Till the jewels of Light Heavenly Men beaming bright Appeard as One Man"And this One Man is the mild, forgiving Christ, who welcomes Blake to his fold, as one of those who have awakened from 'Newton's sleep', or the single vision of materialism:"
Soft he smild And I heard his voice Mild Saying This is My Fold O thou Ram hornd with gold Who awakest from sleep On the sides of the Deep"Then the vision is over and the Saviour's voice fades, Blake passes into the state of enriched 'innocence' which he has portrayed in Songs of Innocence. Now all things have been permanently transformed, by his glimpse of the infinite, into objects of joy:"
I remaind as a Child All I ever had known Before me bright Shone
