Famous quotes containing the word heart:

    He teaches me to set my heart on nothing. He detaches my mind from friends and relations; and I could watch on as brother, children, mother, and wife all died, and not care in the least.
    Molière [Jean Baptiste Poquelin] (1622–1673)

    Though I knit my brow,
    my gaze is fixed
    longingly
    anyway.
    Though I check my tongue,
    this tortured face of mine
    dissolves in a smile.
    Though I drive my heart to hardness,
    my body bears
    the gooseflesh
    of desire.
    When I see that man,
    how on earth
    can my anger
    survive?
    Amaru (c. seventh century A.D.)

    For the sword outwears its sheath,
    And the soul wears out the breast.
    And the heart must pause to breathe,
    And love itself have rest.
    George Gordon Noel Byron (1788–1824)
