Famous quotes containing the word heart:

    While I wrought out these fitful Danaan rhymes,
    My heart would brim with dreams about the times
    When we bent down above the fading coals
    And talked of the dark folk who live in souls
    Of passionate men, like bats in the dead trees....
    William Butler Yeats (1865–1939)

    I saw the spires of Oxford
    As I was passing by,
    The grey spires of Oxford
    Against a pearl-grey sky;
    My heart was with the Oxford men
    Who went abroad to die.
    Winifred M. Letts (1887–1972)

    Now wae to thee, thou cruel lord,
    A bluidy man I trow thou be;
    For mony a heart thou hast made sair
    That ne’er did wrong to thine or thee.
    Robert Burns (1759–1796)
