Mbh 12.201.2

"'Bhishma said, "In this connection is cited the old narrative of the discourse between that lord of creatures, viz., Manu, and the great Rishi, Vrihaspati. In days of old, the foremost of celestial Rishis, viz., Vrihaspati, who was a disciple of Manu, bowed to his preceptor and addressing that lord and first of all creatures, said, 'What is the cause (of the universe)? Whence have the ordinances (about sacrifices and other pious observances) flowed? What are those fruits which the learned say are attached to Knowledge? Tell me also truly, O illustrious one, what is that which the very Vedas have not been able to reveal? What are those fruits which are adored by eminent personages conversant with the science of Artha, with the Vedas, and with the Mantras, through sacrifices and plentiful gifts of kine? Whence do those fruits arise? Where are they to be found? Tell me also this old history, viz., whence have the earth, all earthly objects, wind, sky, aquatic creatures, water, heaven, and the denizens of heaven, all sprung? Man's inclinations tend towards that object about which he seeks knowledge. I have no knowledge of that Ancient and Supreme one. How shall I rescue myself from a false display of inclinations towards Him?[650] The Riks, all the Samanas, all the Yajuses, the Chhandas, Astronomy, Nirukta, Grammar, Sankalpa, and Siksha, I have studied. But I have no knowledge of the nature of the great creatures (the five primal elements) that enter into the composition of everything.[651] Tell me all I have asked thee, by using only simple assertions and distinguishing adjectives or attributes. Tell me what the fruits are of Knowledge and what those fruits that are attached to sacrifices and other religious rites. Explain to me how also an embodied being departs from his body and how he attains to another body.'
