yasya nāgavadhūhastair lepitaṃ haricandanam
muhuḥ śvāsānilāpāstaṃ yāti dikṣūdavāsatām //

Śesha bears the entire world, like a diadem, upon his head, and he is the foundation on which the seven Pátálas rest. His power, his glory, his form, his nature, cannot be described, cannot he comprehended by the gods themselves. Who shall recount his might, who wears this whole earth, like a garland of flowers, tinged of a purple dye by the radiance of the jewels of his crests. When Ananta, his eyes rolling with intoxication, yawns, then earth, with all her woods, and mountains, and seas, and rivers, trembles. Gandharbas, Apsarasas, Siddhas, Kinnaras, Uragas, and Chárańas are unequal to hymn his praises, and therefore he is called the infinite (Ananta), the imperishable. The sandal paste, that is ground by the wives of the snake-gods, is scattered abroad by his breath, and sheds perfume around the skies.
