Famous quotes containing the words thread and/or form:

    “There’s something like a line of gold thread running through a man’s words when he talks to his daughter, and gradually over the years it gets to be long enough for you pick up in your hands and weave into a cloth that feels like love itself. It’s another thing, though, to hold up that cloth for inspection.”
    —John Gregory Brown (20th century)

    “For Mercy has a human heart,
    Pity, a human face;
    And Love, the human form divine,
    And Peace, the human dress.”
    —William Blake (1757–1827)
