“Love is a light that never dwelleth in a heart possessed by fear.”

"If the mystic knowers be of those who have reached to the beauty of the Beloved One (Mahbúb), this station is the apex of consciousness and the secret of divine guidance. This is the center of the mystery: “He doth what He willeth, ordaineth what He pleaseth.” 1

Were all the denizens of earth and heaven to unravel this shining allusion, this darksome riddle, until the Day when the Trumpet soundeth, yet would they fail to comprehend even a letter thereof, for this is the station of God’s immutable decree, His foreordained mystery. Hence, when searchers inquired of this, He made reply, “This is a bottomless sea which none shall ever fathom.” 2 And they asked again, and He answered, “It is the blackest of nights through which none can find his way.”

Whoso knoweth this secret will assuredly hide it, and were he to reveal but its faintest trace they would nail him to the cross. Yet, by the Living God, were there any true seeker, I would divulge it to him; for they have said: “Love is a light that never dwelleth in a heart possessed by fear.”

Verily, the wayfarer who journeyeth unto God, unto the Crimson Pillar in the snow-white path, will never reach unto his heavenly goal unless he abandoneth all that men possess: “And if he feareth not God, God will make him to fear all things; whereas all things fear him who feareth God.” 3
