Famous quotes containing the word heart:

    All is changed. All looks strange to me and gives me a feeling which I would rather get away from, although I know it to be the carrying out of natural laws. And I am not complaining. I am doing the same as many old people have done, I suppose, who have led an active life and suddenly find themselves living without a purpose. Oh, my heart is so full. I could write a big book on the subject of going out of this world gracefully.
    Maria D. Brown (1827–1927)

    I—though heart might find relief
    Did I become a Christian man and choose for my belief
    What seems most welcome in the tomb—play a predestined part.
    Homer is my example and his unchristened heart.
    William Butler Yeats (1865–1939)

    O heart the winds have shaken, the unappeasable host
    Is comelier than candles at Mother Mary’s feet.
    William Butler Yeats (1865–1939)
