Blake's Myth: The Beginning and the Fall

Originally you were only an Idea in the mind of Your Maker. In the
Beginning, Like the Nymphs of you came down the Northern
Gate to a Life of Joy and Woe into the Sea of Time and Space (you
put on the garment, or entered the Tent (or Grave); the Garment, the
Tent, the Sea is the World in which we find ourselves: (Ulro)).

But before that happened completely, you lived a Life of Innocence
when you were still One (still a part of the Infinite Oneness of Eternal
Reality). People exposed to Blake rarely get beyond the Songs of
Innocence-- loved by everyone.

We might say that Blake remained writing songs of innocence until
about the time he was married.
