182.55

samāḥ sahasrāṇi tu sapta vai jale mriyel labhed dvādaśavahnimadhye /
tyajaṃstanuṃ śūravṛttyā narendra śakrātithyaṃ yāti vai martyadharmā //

If a mortal man should die in the water, [he dwells in heaven] for seven thousand years; in the midst of fire, he would obtain twelve [thousand];
abandoning his body with a hero's conduct, O king, he receives the hospitality of Indra.
