“If faith is a mystery, it is because its nature is inexpressible in the measure that it is profound, for it is not possible to convey fully by words this vision which is still blind, and this blindness which already sees.”

As quoted in "Husayn ibn Mansur al-Hallaj" at Sidi Muhammad Press http://www.sufimaster.org/teachings/husayn.htm
Context: Love is in the pleasure of possession, but in the Love of Allah there is no pleasure of possession, because the stations of the Reality are wonderment, the cancelling of the debt which is owed, and the blinding of vision. The Love of the human being for God is a reverence which penetrates the very depths of his being, and which is not permitted to be given except to Allah alone. The Love of Allah for the human being is that He Himself gives proof of Himself, not revealing Himself to anything that is not He.
