Trembling I sit day and night, my friends are astonish'd at me.
Yet they forgive my wanderings, I rest not from my great task!
To open the Eternal Worlds, to open the immortal Eyes
Of Man inwards into the Worlds of Thought: into Eternity
Ever expanding in the Bosom of God, the Human Imagination
O Saviour pour upon me thy Spirit of meekness & love:
Annihilate the Selfhood in me, be thou all my life!
Guide thou my hand which trembles exceedingly upon the rock of ages [...]
I write in South Molton Street what I both feel and know,
In regions of Humanity, in London's opening streets.
~ William Blake, Jerusalem
