Famous quotes containing the word heart:

    I cannot find language of sufficient energy to convey my sense of the sacredness of private integrity. All men, all things, the state, the church, yea the friends of the heart are phantasms and unreal beside the sanctuary of the heart. With so much awe, with so much fear, let it be respected.
    Ralph Waldo Emerson (1803–1882)

    Continued traveling is far from productive. It begins with wearing away the soles of the shoes, and making the feet sore, and ere long it will wear a man clean up, after making his heart sore into the bargain. I have observed that the afterlife of those who have traveled much is very pathetic.
    Henry David Thoreau (1817–1862)

    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)
