Mbh 1.31.4a

“Once upon a time, when the lord of creation, Kasyapa, was engaged in a sacrifice from desire of offspring, the Rishis, the gods, and the Gandharvas, all gave him help. And Indra was appointed by Kasyapa to bring the sacrificial fuel; and with him those ascetics the Valakhilyas, and all the other deities. And the lord Indra, taking up according to his own strength, a weight that was mountain-like, brought it without any fatigue. And he saw on the way some Rishis, of bodies of the measure of the thumb, all together carrying one single stalk of a Palasa (Butea frondosa) leaf. And those Rishis were, from want of food, very lean and almost merged in their own bodies. And they were so weak that they were much afflicted when sunk in the water that collected in an indentation on the road produced by the hoof of a cow. And Purandara, proud of his strength, beheld them with surprise, and laughing at them in derision soon left them behind insulting them, besides, by passing over their heads. And those Rishis being thus insulted were filled with rage and sorrow. And they made preparations for a great sacrifice at which Indra was terrified. Hear, O Saunaka, of the wish for accomplishment of which those vow-observing wise, and excellent ascetics poured clarified butter of the sacrificial fire with loudly uttered mantras, ‘There shall be another Indra of all gods, capable of going everywhere at will, and of mustering at will any measure of energy, and striking tear into the (present) king of the gods. By the fruit of our ascetic penance, let one arise, fleet as the mind, and fierce withal.’ And the lord of the celestials of a hundred sacrifices, having come to know of this, became very much alarmed and sought the protection of the vow-observing Kasyapa. And the Prajapati Kasyapa, hearing everything from Indra, went to the Valakhilyas and asked them if their sacrifice had been successful. And those truth-speaking Rishis replied to him, saying, ‘Let it be as thou sayest!’
