Famous quotes containing the word heart:

    I am black: I am the incarnation of a complete fusion with the world, an intuitive understanding of the earth, an abandonment of my ego in the heart of the cosmos, and no white man, no matter how intelligent he may be, can ever understand Louis Armstrong and the music of the Congo.

    A man cannot know himself better than by attending to the feelings of his heart and to his external actions, from which he may with tolerable certainty judge “what manner of person he is.” I have therefore determined to keep a daily journal.
    James Boswell (1740–1795)

    But the heart refuses to be imprisoned; in its first and narrowest pulses it already tends outward with a vast force and to immense and innumerable expansions.
    Ralph Waldo Emerson (1803–1882)
