"Here indeed is the true lover," said the Nightingale. "What I sing of, he suffers — what is joy to me, to him is pain. Surely Love is a wonderful thing. It is more precious than emeralds, and dearer than fine opals. Pearls and pomegranates cannot buy it, nor is it set forth in the marketplace. It may not be purchased of the merchants, nor can it be weighed out in the balance for gold."
