Indra said, 'Five (pañka, m. f., quinque) for me!' Then the others found no pair, for after that (numeral four) there is no pair, for then both (masculine and feminine) are pañka. Thereupon the Asuras were defeated and lost everything, and the gods won everything from the Asuras, and stripped their rivals, the Asuras, of everything.
