William Blake’s wife reminded the poet in old age, “You know, dear, the first time you saw God was when you were four years old, and He put His head to the window and set you a-screaming.” Allen Ginsberg said that in 1948, while a senior at Columbia University, he was visited by the voice of Blake, which revealed to him the power of poetry—this was after he had read one of Blake’s poems while masturbating.
