Piercing

Saying this, the son of Drona shot at Satyaki an
excellent and straight arrow possessed of the effulgence of the sun, even as Sakra had hurled in days of
yore his thunder at the Asura Vritra. Thus shot by Aswatthaman, that arrow, piercing through the armour
of Satyaki, and passing through his body, entered the earth like a hissing snake entering its hole. His
armour pierced through, the heroic Satyaki, like an elephant deeply struck with the hook, became bathed
in blood that flowed from his wound.
