Their souls are purified by [the Qur1an’s] exoteric sense (zahir) because it is water which flows copiously and the thirst of their hearts is quenched by its inner sense (batin) because it is a surging sea. When they wish to dive in order to extract the pearls of its secrets the water crashes over them and they are submerged in its current. The riverbeds of insights ( fuhum) flow from this deluge according to their capacities, while the streams of realizations (2uqul) proceed from its rivers. The riverbeds bring forth piercing jewels and pearls upon the shores and the streams cause flowers and fruit to bloom upon the banks. Hearts take from the overflow as much as they can, filling their laps and sleeves, while souls set out to harvest the fruits and lights, grateful for finding them, their desires fulfilled by them.5
