Famous quotes containing the word heart:

    Look into the world—how often do you behold a sordid wretch, whose straight heart is open to no man’s affliction, taking shelter behind an appearance of piety, and putting on the garb of religion, which none but the merciful and compassionate have a title to wear.
    Laurence Sterne (1713–1768)

    ... [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)

    Eternall God, O thou that onely art
    The sacred Fountain of eternall light,
    And blessed Loadstone of my better part;
    O thou my heart’s desire, my soul’s delight,
    Reflect upon my soul, and touch my heart,
    And then my heart shall prize no good above thee;
    And then my soul shall know thee; knowing, love thee;
    And then my trembling thoughts shall never start
    From thy commands, or swerve the least degree,
    Or once presume to move, but as they move in thee.
    Francis Quarles (1592–1644)
