Usha
Usha has been described as far – extending, many – tinted, brilliant Dawn, whose abode is unknown She harnesses her chariots from afar and comes in radiance and glory She is the young, the white-robed daughter of the sky, and the queen of all earthly treasures She is like the careful mistress of the house who rouses everyone from his slumbers and sends him to his work Yet she is radiant as a bride decorated by her mother for the auspicious ceremony, and displaying her charms to the view
Such are the fond epithets and beautiful similes with which the Hindu Aryans greeted the fresh and lovely mornings of a tropical sky
