Mysticism, by Evelyn Underhill, [1911],

 Under whatsoever symbols they have objectified their quest, none of these seekers have ever been able to assure the world that they have found, seen face to face, the Reality behind the veil. But if we may trust the reports of the mystics—and they are reports given with a strange accent of certainty and good faith—they have succeeded where all these others have failed, in establishing immediate communication between the spirit of man, entangled as they declare amongst material things, and that “only Reality,” that immaterial and final Being, which some philosophers call the Absolute, and most theologians call God. This, they say—and here many who are not mystics agree with them—is the hidden Truth which is the object of man’s craving; the only satisfying goal of his quest.
