sa tada labdha-tirtho ’pi

 na babadhe nirayudham

manayan sa mrdhe dharmam

 visvaksenam prakopayan

 

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

Even though the demon had an excellent opportunity to strike his unarmed foe without obstruction, he respected the law of single combat, thereby kindling the fury of the Supreme Lord.
