3.5.15

tad asya kauṣārava śarma-dātur hareḥ kathām eva kathāsu sāram /
uddhṛtya puṣpebhya ivārta-bandho śivāya naḥ kīrtaya tīrtha-kīrteḥ //

15. Therefore, Kausharava, O friend of the distressed, be pleased to extract as from flowersand tell us for our good, only the story of Sri Hari, the essence of all stories—of Hari who is the giver of happiness and whose fame purifies (the world).
