This is a small bit from William Blake's Auguries of Innocence.
Every night and every morn Some to misery are born, Every morn and every night Some are born to sweet delight. Some are born to sweet delight, Some are born to endless night. We are led to believe a lie When we see not thro' the eye, Which was born in a night to perish in a night, When the soul slept in beams of light. God appears, and God is light, To those poor souls who dwell in night; But does a human form display To those who dwell in realms of day.
