Srimad Bhagavadgita, Chapter 11, Shlokas 22-30

Those who are the Rudras, the Adityas, the Vasus and the Sadhyas [sadhyas: A particular class of celestial beings], the Visve (devas), the two Asvins, the Maruts and the Usmapas, and hosts of Gandharvas, Yaksas, demons and Siddhas-all of those very ones gaze at You, being indeed struck with wonder.
O mighty-armed One, seeing Your immense form with many mouths and eyes, having numerous arms, thighs and feet, with many bellies, and fearful with many teeth, the creatures are struck with terror, and so am I.
O Visnu, verily, seeing Your form touching heaven, blazing, with many colours, open-mouthed, with fiery large eyes, I , becoming terrified in my mind, do not find steadiness and peace.
Having merely seen Your mouths made terrible with (their) teeth and resembling the fire of Dissolution, I have lost the sense of direction and find no comfort. Be gracious, O Lord of gods, O Abode of the Universe.
And into You (enter) all those sons of Dhrtarastra along with multitudes of the rulers of the earth; (also) Bhisma, Drona and that son of a Suta (Karna), together with even our prominent warriors.
They rapidly enter into Your terrible mouths with cruel teethes! Some are seen sticking in the gaps between the teeth, with their heads crushed!
As the numerous currents of the waters of rivers rush towards the sea alone so also do those heroes of the human world enter into Your blazing mouths.
As moths enter with increased haste into a glowing fire for destruction, in that very way do the creatures enter into Your mouths too, with increased hurry for destruction.
You lick Your lips while devouring all the creatures from every side with flaming mouths which are completely filling the entire world with heat.
