Bhagavatapurana 10.69.44

44. Thus adopting the course of human life, Narayana appeared in various forms for the good of the whole world and delightfully spent the time worshipped by the fifteen thousand excellent damsels with their bashful and friendly looks and smiles.

45. He who sings of, or listens to, or views with approbation those exploits impossible for others, which Hari, the cause of the world, its origin, destruction and existence, performed, will acquire devotion to the Almighty Lord who leads him to Moksha.
