ブレイクの「無垢と経験の歌」について Regarding Blake's Songs of Innocence and Experience

Blake had it backwards. Perhaps he realised it later too and put the two into one which is a wise thing when you are unsure whether you are seeing causation and results or are a continuous, indistinguishable process that people inserts into it some points of references which are called causes and results.
Innocence: in the beginning, God made Tyger. He was the most beautiful, strongest and purest existence in earth. He eats only what his souls tells him to do. He drinks only what his mind tells him to do. He mates with only what he thinks are beautiful. He relieves himself in joy and would not turn back to look at the filth born from him. He is perfect. He is the child. He is unfallen Orc, Cor---heart..
Experience: God is jealous….
God is jealous of his beautiful mane, his golden skin.
His strong sinews, his boyish laughter.
He is jealous of the rosy fragrant ambrosial meat with clear black ichor wine he consumes. He is jealous of his host and spirit.
He is jealous of him doing what he wills…such abandon…such freedom…such perfect willpower… 
And he is jealous of his mate…..the blue blue earth, with clothing made of green grass, belts and bands made with yellow leaves, gems and jeweleries of red and black fruits, of her pale and sandy thigh, pink and tender hands…her dark, humid, warm womb…
Thus God killed his son in jealousy like Abel killed Cain; and donned his body-garment for himself…
With the barbed biting, blood-drawing, hard and tough arrow of REALITY.
So he can deceive and seduce the beautiful earth to submit to his impotent Will…so he could make a kingdom, a stolen kingdom from the righteous King betrayed and killed by him in cold blood.
The erstwhile all-mighty, all-wandering, all-joyous King. 
And the worms, pale elfin worms that begot by the putrefied lymph, fat, and tears of the dead Tyger's body learnt to walk on their feet, talk with their tongue, and hold tools with their hand, with the nutrients and water stolen from the Tyger---they become men.
This is a sad experience.
………………….
In the beginning, there was a perfect Boy called Peter Pan;
flying in the night, free as wind; though,
He got struck down by a paper aeroplane sent by God in his cruel play.
And from his dead body crawled out the humble beast, pale, necrophagic, stupid.
Which we call ourselves----(from the bodies of dead boys) Grown Up men.

(But in the end---who is the father, who is the child?
We grew from boys, and are men;
but those who grew from us, our children;
are they not what we grew up to  be-----more mature men?

are they not our guardians and makers---are they not our lords?
are we not intemperate children who are perfect and better than them--
and are they not impotent and jealous parents who want to steal from us,
-----and our Father?
"Child is the father of Man" (Wordsworth). )

Are not grown-ups Peter Pan, and are not children Wendy?
