From Solitude (1830), by Johann von Zimmermann.

The highest happiness which is capable of being enjoyed in this world, consists in peace of mind. The wise mortal who renounces the tumults of the world, restrains his desires and inclinations, resigns himself to the dispensations of his Creator, and looks with an eye of pity on the frailties of his fellow creatures; whose greatest pleasure is to listen among the rocks to the soft murmurs of a cascade; to inhale, as he walks along the plains, the refreshing breezes of the zephyrs; and to dwell in the surrounding woods, on the melodious accents of the aerial choristers; may, by the simple feelings of his heart, obtain this invaluable blessing.
