Famous quotes containing the word heart:

    Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.
    Ralph Waldo Emerson (1803–1882)

    What of the heart without her? Nay, poor heart,
    Of thee what word remains ere speech be still?
    A wayfarer by barren ways and chill,
    Steep ways and weary, without her thou art,
    Where the long cloud, the long wood’s counterpart,
    Sheds doubled darkness up the labouring hill.
    Dante Gabriel Rossetti (1828–1882)

    It is not worth the while to let our imperfections disturb us always. The conscience really does not, and ought not to monopolize the whole of our lives, any more than the heart or the head. It is as liable to disease as any other part.
    Henry David Thoreau (1817–1862)
