Famous quotes containing the word heart:

    I’m folding up my little dreams
    Within my heart tonight,
    And praying I may soon forget
    The torture of their sight.

    The Danube to the Severn gave
    The darken’d heart that beat no more;
    They laid him by the pleasant shore,
    And in the hearing of the wave.
    Alfred Tennyson (1809–1892)

    O hiding hair and dewy eyes,
    I am no more with life and death,
    My heart upon his warm heart lies,
    My breath is mixed into his breath.
