Famous quotes containing the words principal and/or meridian:

    With a balanced combination of the two principal energies from mother and father, a girl can both be in touch with her womanly strengths and be a powerful force in the world—strong and nurturing, decisive and caring, goal- oriented and aware of the needs of others. She has the courage to voice what she thinks and feels and the strength to follow her destiny.

    to these
    Hale dead and deathless do the women of the hill
    Love for ever meridian through the courters’ trees
    And the daughters of darkness flame like Fawkes fires still.
