'But if you wish to know how these things come about ask grace not instruction, desire not understanding, the groaning of prayer not diligent reading, the Spouse not the teacher, God not man, darkness not clarity, not light but the fire that totally enflames and carries us into God by ecstatic unctions and burning affections. This fire is God and his furnace is in Jerusalem...' --Bonaventure, 1217-1274
