Kitab-i-Aqdas/Elder178

This is not something to be played with by your illusions. This is not a Station into which every illusioned coward enters. By God, this is the training-place (midmar) for unveiling and separation (from the world) and the race-ground (maydan) of Vision and Exaltation. Only the horsemen of the Merciful, who disregard the (realm of) possibility, go about in it. Those are the helpers of God in the earth and in the Sunrise-places of power among the worlds.
