Her foster-parents looked at Undine in surprise, for they had neither seen the rings nor known that their foster-child had any jewels in her possession.
Then the maiden, seeing their astonishment, told how her parents had stitched the rings into the little garments she had worn when first she came to them, a tiny child. 'They bid me also tell no one that they had given me these precious gems until the evening of my wedding-day.'
Meanwhile the priest had clad himself again in his own garments, and lighting the candles, he called to Huldbrand and the maiden to come and kneel before him.
Gladly they obeyed, and then in the little cottage were heard the solemn words of the marriage service, and Undine became the wife of Huldbrand, the knight of Ringstetten.
The maiden had been unusually quiet as she listened to the solemn words of the marriage service, but now a spirit of mischief seemed to seize her. She laughed and danced, she played childish tricks upon her husband, her foster-parents, even upon the priest himself.
Her foster-mother would have rebuked Undine as of old, but the knight silenced her, for Undine was now his wife. Yet he himself was little pleased with her behaviour. When Undine saw a frown upon his brow, it is true that she would grow quieter, and sitting near him, would for a little while smooth his brow with her soft white hand. Soon, however, a new fancy would take hold of her, she would jump up, and her tricks would grow even more vexing than before.
Then the priest spoke, and his voice was grave.
'Lady, you are fair to look on, but I pray you to cease these foolish ways, lest your soul become less beautiful than your face.'
Undine's laughter ceased. After a while she looked at the priest and asked in a timid whisper, 'What is this thing which you call a soul, holy Father?'
Over the little kitchen a hush fell as the holy man answered, 'How can I tell you what this strange thing which we call our soul really is? Yet can I tell you why God gives us this great gift. It is that we may learn to know and love Him. Our bodies will grow old, and we will lay them aside as a garment which we no longer need, while our souls will live and dwell with Him for ever.'
Undine's eyes grew sad, tears streamed down her cheek. 'Ah,' she sobbed, 'I have no soul, no soul. I think it would hurt me to have a soul, yet fain would I have one.'
