His collection of poems "White Stains" is just amazing as well - mostly speaking about human secretions of all kinds and ingesting them.
Edit:"White Stains, a collection of Crowley's poetry praised by W.B. Yeats, published in paperback for the first time, has been called 'the filthiest book of verse ever written' and of the first edition of 100 numbered copies, 83 were pulped and burned by Her Majesty's Customs in 1924."
