Shanti Parva 343.11

As butter is raised from curds, sandal-wood from the mountains of Malaya, the Aranyakas from the Vedas, and ambrosia from all the medicinal herbs, similarly, O ocean of austerities, has this discourse that is like ambrosia and that has Narayana for its object, been raised by you, O Brahmana, from various histories and Puranas existing in the world.
