From The Candle of Vision (1918), by AE (George William Russell).

So the lover of Earth obtains his reward, and little by little the veil is lifted of an inexhaustible beauty and majesty. It may be he will be tranced in some spiritual communion, or will find his being overflowing into the being of the elements, or become aware that they are breathing their life into his own. Or Earth may become on an instant all faery to him, and earth and air resound with the music of its invisible people. Or the trees and rocks may waver before his eyes and become transparent, revealing what creatures were hidden from him by the curtain, and he will know as the ancients did of dryad and hamadryad, of genii of wood and mountain. Or earth may suddenly blaze about him with supernatural light in some lonely spot amid the hills, and he will find he stands as the prophet in a place that is holy ground, and he may breathe the intoxicating exhalations as did the sibyls of old. Or his love may hurry him away in dream to share in deeper mysteries, and he may see the palace chambers of nature where the wise ones dwell in secret, looking out over the nations, breathing power into this man’s heart or that man’s brain, on any who appear to their vision to wear the colour of truth. So gradually the earth lover realises the golden world is all about him in imperishable beauty, and he may pass from the vision to the profounder beauty of being, and know an eternal love is within and around him, pressing upon him and sustaining with infinite tenderness his body, his soul and his spirit.
