Famous quotes containing the word heart:

    blue bead on the wick,
    there’s that in me that
    burns and chills, blackening
    my heart with its soot,
    I think sometimes not Apollo heard me
    but a different god.
    Denise Levertov (b. 1923)

    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)

    I am primarily engaged to myself to be a public servant of all the gods, to demonstrate to all men that there is intelligence and good will at the heart of all things, and even higher and yet higher leadings. These are my engagements; how can your law further or hinder me in what I shall do to men?
    Ralph Waldo Emerson (1803–1882)
