Mbh 13.98.2

"'Bhishma said, "In this connection, O Bharata, is recited the old narrative of the discourse between Manu, that lord of creatures, and Suvarna. There was in days of yore an ascetic, O Bharata, of the name of Suvarna. His complexion was like that of gold and hence he was called Suvarna (the gold-complexioned). Endued with a pure lineage, good behaviour, and excellent accomplishments, he had mastered all the Vedas. Indeed, by the accomplishments he possessed, he succeeded in surpassing many persons of high lineage. One day that learned Brahmana saw Manu, the lord of all creatures, and approached him. Meeting with each other, they made the usual enquiries of politeness. Both of them were firm in the observance of truth. They sat down on the delightful breast of Meru, that mountain of gold. Seated there they began to converse with each other on diverse subjects connected with the high-souled deities and regenerate Rishis and Daityas of ancient times. Then Suvarna, addressing the Self-born Manu, said these words, 'It behoveth thee to answer one question of mine for the benefit of all creatures. O lord of all creatures, the deities are seen to be worshipped with presents of flowers and other good scents. What is this? How has this practice been originated? What also are the merits that attach to it? Do thou discourse to me on this topic.'
