If they disturb his duties on the earth.
(Capesius sits, and is plunged in thought while the vision of Lucifer appears to Maria.)
Lucifer:
Thine effort will not bring thee much reward.
New force begins to stir within his heart
That opes the portal of his soul to me.
Maria, gaze with thy clairvoyant sight
Upon his inmost soul; and there behold
How he doth free himself on spirit-wings
From thy warm loving bonds of work on earth.
