3.131.27

na vidyate yadā māṃsaṃ kapotena samaṃ dhṛtam |
tata utkṛttamāṃso'sāvāruroha svayaṃ tulām || 27 ||

"Lomasa said, 'Saying this, O mighty son of Kunti, the highly virtuous king cut off a portion of his own flesh, and placed it in a balance, against the pigeon. But when he found that pigeon exceeded his flesh in weight, he once more cut off another portion of his flesh, and added it to the former. When portion after portion had been repeatedly added to weigh against the pigeon, and no more flesh was left on his body, he mounted the scale himself, utterly devoid of flesh.
