“Vaisampayana said, ‘That bull among the Bharatas, Arjuna, hearing these words of the Gandharva, was inspired with feelings of devotion and stood shes (???--JBH), killing deer and wild boars. Once on a time, while out in quest of deer, the king became weak with exertion and thirst. The monarch arrived in that state at the asylum of Vasishtha, and the blessed and illustrious Rishi beholding him arrive, reverenced with his homage that best of men, king Viswamitra. And O Bharata, the Rishi saluted the monarch by offering him water to wash his face and feet with, and Arghya, and wild fruits, and clarified butter. For the illustrious Rishi had a cow yielding anything that was desired of her. When she was addressed, saying, ‘O give’,--she always yielded the article that was sought. And she yielded various fruits and corn, wild or grown in gardens and fields, and milk, and many excellent nutritive viands full of six different kinds of juice (taste?) and like unto nectar itself, and various other kinds of enjoyable things, O Arjuna, of ambrosial taste for drinking and eating, and for licking and sucking, and also many precious gems and robes of various kinds. With these desirable objects in profusion the monarch was worshipped. And the king with his minister and troops became highly pleased. And the monarch wondered much, beholding that cow with six elevated limbs and the beautiful flanks and hips, and five limbs that were broad, and eyes prominent like those of the frog and beautiful in size, and high udders, and faultless make, and straight and uplifted ears, and handsome horns, and well-developed head and neck.
