Henry Wadsworth Longfellow - Rondel lyrics

Love, love, what wilt thou with this heart of mine?   Naught see I fixed or sure in thee! I do not know thee,—nor what deeds are thine: Love, love, what wilt thou with this heart of mine?   Naught see I fixed or sure in thee! Shall I be mute, or vows with prayers combine?   Ye who are blessed in loving, tell it me: Love, love, what wilt thou with this heart of mine?   Naught see I permanent or sure in thee!
