The Gandharva Vishvavasu, a master of the Vedanta Shastra, desirous, O king, of ascertaining what is good for the Brahmanas in this knowledge and what truth is in it, and what is the excellent object of this knowledge, once catechised me. He put to me altogether twentyfour questions, O king, regarding the Vedas. Finally, he put to me a question, numbered twenty-fifth which relates to ratioscination. These questions are as follow:-What is universe and what is non-universe? What is Ashva and what Ashva? What is Mitra? What is Varuna?
