Then the Dronakalasa with (Vâg. S. VII, 29), 'Who (ka) art thou? Which one art thou?'--Ka is Pragâpati;--'Whose (kasya, or Ka's) art thou? who (ka) art thou by name?'--Ka ('who') by name is Pragâpati;--'Thou upon whose name we have thought,' for he indeed thinks upon his name;--'Thou whom we have gladdened with Soma;'--for he indeed gladdens him with Soma. Having drawn the Âsvina cup, he prays for blessing part after part (of the sacrifice) with, 'May I be abundantly supplied with offspring,' thereby he prays for offspring;--'abundantly supplied with men,' thereby he prays for men (heroes);--'abundantly supplied with food!' thereby he prays for prosperity.
