And thus Hugh turned more and more away from the critical apprehension of imaginative literature, to the mystical apprehension of it. A critical apprehension of it was indeed necessary, for it initiated one into the secrets of expression and of structure, in which the force of personality was largely displayed, taking shape from the thought in them, as clothes take shape from their wearers. But deeper still lay the mystical interpretation. In the world of books he heard the voice of the soul, sometimes lamenting in desolate places, sometimes singing blithely to itself, as a shepherd sings upon a headland, in sight of the blue sea; sometimes there came a thrill of rapture into the voice, when the spirit was filled to the brim with the unclouded joys of the opening world, the scent of flowers, the whispering of foliage in great woods, the sweet harmonies of musical chords, the glance of beloved eyes, or the accents of some desired voice; and then again all this would fade and pale, and the soul would sit wearied out, lamenting its vanished dreams and the delicate delights of the springtime, in some wild valley overhung with dark mountains, under the dreadful and inscrutable eye of God. Life, how insupportable, how beautiful it seemed! Full of treasures and terrors alike, its joys and its woes alike unutterable. The strangest thing of all, that the mind of man was capable of seeing that there was a secret, a mystery about it all; could desire so passionately to know it and to be satisfied, and yet forbidden even dimly to discern its essence.
