They do not know what it is to feel and manifest that intense, eager, longing, craving, insistent, demanding, ravenous Desire which is akin to the persistent, insistent, ardent, overwhelming desire of the drowning man for a breath of air; of the shipwrecked or desert-lost man for a drink of water; of the famished man for bread and meat'' (Robert Collier)
