aratnī dve aratnibhyāḿ
jānubhyāḿ caiva jānunī
śiraḥ śīrṣṇorasoras tāv
anyonyam abhijaghnatuḥ
aratni -- against the opponent's fists; dve -- two; aratnibhyam -- their fists; janubhyam -- their knees; ca eva -- also; januni -- against the opponent's knees; sirah -- head; sirshna -- with head; urasa -- with chest; urah -- chest; tau -- they in pairs; anyonyam -- each other; abhijaghnatuh -- struck.
The word aratni in this verse may indicate the elbow as well as the fist. Thus blows were perhaps also struck with the elbow, a technique seen today in various martial arts.
