SB 9.15.33
atharjunah pañca-satesu bahubhir
dhanuhsu banan yugapat sa sandadhe
ramaya ramo ’stra-bhrtam samagranis
tany eka-dhanvesubhir acchinat samam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Then Kartaviryarjuna, with his one thousand arms, simultaneously fixed arrows on five hundred bows to kill Lord Parasurama. But Lord Parasurama, the best of fighters, released enough arrows with only one bow to cut to pieces immediately all the arrows and bows in the hands of Kartaviryarjuna.
