Famous quotes containing the word heart:

    ... [the] special relation of women to children, in which the heart of the world has always felt there was something sacred, serves to impress upon women certain tendencies, to endow them with certain virtues ... which will render them of special value in public affairs.
    Mary Putnam Jacobi (1842–1906)

    My heart is like a singing bird
    Whose nest is in a watered shoot;
    My heart is like an apple-tree
    Whose boughs are bent with thickset fruit;
    My heart is like a rainbow shell
    That paddles in a halcyon sea;
    Christina Georgina Rossetti (1830–1894)

    Home—that blessed word, which opens to the human heart the most perfect glimpse of Heaven, and helps to carry it thither, as on an angel’s wings.
    Lydia M. Child (1802–1880)
