The Perception tank is a 100% ultra soft cotton tank featuring a famous quote from William Blake's 'The Marriage of Heaven and Hell.' The quote was used in the title of Aldous Huxley's book 'The Doors of Perception' published in 1954 which is an autobiographical account of his experiences onMescaline. This in turn inspired the name of the band 'The Doors.' The quote reads, 'If the doors of perception were cleansed every thing would appear to man as it is, Infinite."
