bhīṣma uvāca |
atra yā māmakī buddhiḥ śrūyatāṃ yadi rocate |
kṣipraṃ balacaturbhāgaṃ gṛhya gaccha puraṃ prati |
tato'paraścaturbhāgo gāḥ samādāya gacchatu || 16 ||

"Bhishma said, 'Listen to what I regard as proper, if it pleases thee. I should always say what is for thy good, O Kaurava. Proceed thou towards the capital, without loss of time, taking with thee a fourth part of the army. And let another fourth march, escorting the kine. With half the troops we will fight the Pandava. Myself and Drona, and Karna and Aswatthaman and Kripa will resolutely withstand Vibhatsu, or the king of the Matsyas, or Indra himself, if he approaches. Indeed, we will withstand any of these like the bank withstanding the surging sea.'
