Famous quotes containing the words path and/or integral:

    “It is the way unseen, the certain route,
    Where ever bound, yet thou art ever free;
    The path of Him, whose perfect law of love
    Bids spheres and atoms in just order move.”
    —Jones Very (1831–1880)

    “Painting myself for others, I have painted my inward self with colors clearer than my original ones. I have no more made my book than my book has made me—a book consubstantial with its author, concerned with my own self, an integral part of my life; not concerned with some third-hand, extraneous purpose, like all other books.”
    —Michel de Montaigne (1533–1592)
