“The Gandharva continued, ‘Then the cow of Vasishtha, hearing the word stay, raised her head and neck upward, and became terrible to behold. With eyes red with rage and lowing repeatedly, she then attacked Viswamitra’s troops on all sides. Afflicted with their stripes and running hither and thither with those red eyes of hers, her wrath increased.
