Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
“Therefore it is our duty to kill this Vamanadeva, Lord Visnu. It is our religious principle and the way to serve our master.” After making this decision, the demoniac followers of Maharaja Bali took up their various weapons with a view to killing Vamanadeva.
