nagendranam ananto ’ham
 mrgendrah srngi-damstrinam
asramanam aham turyo
 varnanam prathamo ’nagha
 
Translation: 
 
O sinless Uddhava, among the best of snakes I am Anantadeva, and among those animals with sharp horns or teeth I am the lion. Among the social orders I am the fourth, or the renounced order of life, and among the occupational divisions I am the first, the brahmanas.
