"As the function of the castrum or castellum is not merely to resist a siege, but to compel to Obedience of Law and Order every pagan within range of its riders, so also it is the Way of Chastity to do more than defend its purity against assault. For he is not wholly pure who is imperfect; and perfect is no man in himself without his fulfillment in all possibility."
[Aleister Crowley, Little Essays toward Truth, Chastity.]
