Famous quotes containing the words principal and/or meridian:

    The principal thing children are taught by hearing these lullabies is respect. They are taught to respect certain things in life and certain people. By giving respect, they hope to gain self-respect and through self-respect, they gain the respect of others. Self-respect is one of the qualities my people stress and try to nurture, and one of the controls an Indian has as he grows up. Once you lose your self-respect, you just go down.
    Henry Old Coyote (20th century)

    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.
    Dylan Thomas (1914–1953)
