Famous quotes containing the word heart:

    To fight without hope is to fight with grace,
    The self reconstructed, the false heart repaired.’
    Sir Herbert Read (1893–1968)

    I saw a staring virgin stand
    Where holy Dionysus died,
    And tear the heart out of his side,
    And lay the heart upon her hand
    And bear that beating heart away;
    William Butler Yeats (1865–1939)

    When I was one-and-twenty
    I heard a wise man say,
    “Give crowns and pounds and guineas
    But not your heart away;
    Give pearls away and rubies,
    But keep your fancy free.”
    But I was one-and-twenty,
    No use to talk to me.
    —A.E. (Alfred Edward)
