I love the amniotic fluid when it spills out of the bag. I love the kidney with its painful gallstones, its gravel and whatnot; I love the urine that pours out scalding and the clap that runs endlessly; I love the words of hysterics and the sentences that flow on like dysentery and mirror all the sick images of the soul; I love the great rivers like the Amazon and the Orinoco, where crazy men like Moravagine float on through dream and legend in an open boat and drown in the blind mouths of the river. I love everything that flows, even the menstrual flow that carries away the seed unfecund. I love scripts that flow, be they hieratic, esoteric, perverse, polymorph, or unilateral. I love everything that flows, everything that has time in it and becoming, that brings us back to the beginning where there is never end: the violence of the prophets, the obscenity that is ecstasy, the wisdom of the fanatic, the priest with his rubber litany, the foul words of the whore, the spittle that floats away in the gutter, the milk of the breast and the bitter honey that pours from the womb, all that is fluid, melting, dissolute and dissolvent, all the pus and dirt that in flowing is purified, that loses its sense of origin, that makes the great circuit toward death and dissolution.
