The mystic purchases a moment of exhilaration with a lifetime of confusion; and the confusion is infectious and destructive. It is confusing and destructive to try and explain anything in terms of anything else, poetry in terms of psychology.
Uncontrolled, the hunger and thirst after God may become an obstacle, cutting off the soul from what it desires. If a man would travel far along the mystic road, he must learn to desire God intensely but in stillness, passively and yet with all his heart and mind and strength.
Just as in earthly life lovers long for the moment when they are able to breathe forth their love for each other, to let their souls blend in a soft whisper, so the mystic longs for the moment when in prayer he can, as it were, creep into God.
Mysticism has been in the past and probably ever will be one of the great powers of the world and it is bad scholarship to pretend the contrary. You may argue against it but you should no more treat it with disrespect than a perfectly cultivated writer would treat (say) the Catholic Church or the Church of Luther no matter how much he disliked them.
